This fruit-based energy gel, once touted for its high-carb intake and low volume, contains about a third of calories than advertised, multiple independent nutritional analyses suggest

For the past 10 years, Spring Energy has provided endurance athletes with energy gels, and more recently drink mixes, made from “real” foods. Athletes looking for wholesome alternatives to more traditional sugar-based gels made in a lab have flocked to Spring’s smoothie-like gels made with fruit and basmati rice.

While Spring products are more expensive than many gels, many athletes have found the tradeoff for high-quality, real food fuel that goes down easily on the run to be worth it. Until now.

After skepticism about the actual contents of Spring’s gels began brewing late last year, it turned into a full-blown controversy this week.

In January 2021, Spring Energy released a game-changing gel, Awesome Sauce. In collaboration with coaches and runners Megan and David Roche (who taste-tested and named the flavor), the applesauce, basmati rice, and sweet potato-based gel was designed to provide endurance athletes with a whopping 180 calories per 54 gram packet.

This high-carb alternative became especially enticing when a study was published in April 2022 reporting that ultrarunners should consume 240 to 360 calories (60-90 grams of carbohydrates) per hour. It’s no surprise that Awesome Sauce (sold at $5 a gel), with its small but surprisingly mighty nutritional content, initially flew off the shelves. It seemed too good to be true.

After several third-party lab tests, that appears to be the case.

In late 2023, runners took to Reddit to discuss their doubts in Awesome Sauce’s nutritional facts, which were printed on the packaging and stated on Spring Energy’s website. Though it’s unclear who first performed a concrete test on the gel, two months ago, Liza Ershova, a Reddit user who uses the username “sriirachamayo”, posted in a thread called “False nutritional info on Spring Energy gels.” Ershova allegedly performed a test “in an environmental chemistry lab” and found that the dry weight of Awesome Sauce is 16g instead of the stated 45. She hypothesized that, “If all of those grams are carbs, that corresponds to about 60 calories, not 180.”

On May 17, German endurance sport speciality shop Sports Hunger released a video stating that they, too, had Awesome Sauce gels tested by a third party, and allegedly found that each packet contains 16g of carbs instead of the 45g that Spring Energy claimed.

“The maker of Spring Energy assures us that they will rework their manufacturing process to ensure that they will again reliably achieve their high numbers that they declare to have,” a Sports Hunger representative says in the video. “We hope that this is really going to happen because we believe that natural food for many of our customers is a great alternative to the regular gels.”

On May 28, ultrarunning coach Jason Koop, who coaches elite athletes sponsored by Spring Energy, posted an Instagram Reel saying that he’d paid for Spring Energy Awesome Sauce to be tested by a third party, RL Food Laboratory Testing in Ferndale, Washington. The results showed that the gels tested contained 76 calories and 18g of carbs. The lab results can be found on Koop’s website. Koop declined to be interviewed for this article.

Other runners have also come forward after attempting to replicate the gels with varying degrees of Awesome Sauce’s ingredients: organic basmati rice, organic apple sauce, apple juice, yams, maple syrup, lemon juice, vanilla, sea salt, and cinnamon—and could not achieve the gel’s original volume of 54g. Their experiments suggest that it’s impossible to fit all of those ingredients into the small Awesome Sauce package while achieving the stated nutritional content.

On May 22, the Ershova shared Spring Energy’s response to their experiment on Reddit: “Our analysis supports the accuracy of our product labeling. However, we will reevaluate to make sure our data is accurate. Although we hoped your experience with our products would have been wholly satisfactory, we recognize that individual needs can vary. Given the wide variety of options available across different brands, we are confident you will find the right product that suits your specific requirements.”

Four days later, on the Sunday of Memorial Day weekend, Spring Energy sent out an email to newsletter subscribers stating:

“In early May we submitted Awesome Sauce for third-party caloric and biomolecular analysis. Although the results indicated that on average our products deliver the designed nutrition value, we have recognized weaknesses in our processes and ingredients which can introduce unwanted variations in some batches.To mitigate those variations in our small batch production, we decided to modify some of the formulations, revise and innovate processes, and re-evaluate ingredient sources. These changes will bring higher quality and more consistency to our products. Enhancements of our products aimed to stabilize their nutrition values are on the horizon, and within the next few weeks, you’ll see the results of our efforts. A new and improved version of Awesome Sauce will soon be available.”

The internet outrage ballooned swiftly.

“‘On average’ – if someone has a beat on where I can grab packets of Awesome Sauce at 75g of carb per pack to allow for the average of their product to be 45g overall, hit my inbox,” @aidstationfireball posted on X. “Excited to taste the new, re-formulated, $7 gels they’ll replace these with.”

David and Megan Roche, the Boulder, Colorado-based running coach couple who collaborated with Spring Energy on Awesome Sauce, discussed the backlash on their podcast. They weren’t involved in the chemical composition and makeup of the gel, they claimed. Rather, they simply proposed the concept of a high-carb gel to their friend Rafal Nazarewicz, the founder and CEO of Spring Energy. They stated they understand the public’s outrage, and Megan added that they “didn’t really use it” during their runs because she didn’t feel that her body was responding to the energy it was supposed to provide.

In addition, the Roches stated on their podcast that they have quietly harbored concerns about Awesome Sauce for years, and while they did not explicitly tell their athletes not to use it, they made a point of promoting other gels instead. (The Roches currently have a financial partnership with The Feed, the online warehouse that sells a wide variety of sports fuel, including Spring Energy.)

David elaborated in a lengthy Instagram post on May 29: “It’s sad and infuriating that the nutrition was wrong, and we are thankful to the really smart people who figured it out on Reddit (including an athlete we coach who started the initial thread). When we described concerns to Spring, we were assured that the nutrition was correct and they followed all FDA regulations. We left the Spring sponsorship years ago, and we never received compensation for proposing the name/doing taste testing (outside of the $200 per month that we both received during the sponsorship). Since then, we have publicly directed athletes to other options for high-carb fueling, while hoping to be a source of love and support in the community. Our podcast covered our concerns as soon as the German lab testing indicated that we wouldn’t be risking making defamatory statements about a business without substantial evidence.”

While concerns around Awesome Sauce instigated this investigation, it’s not the only flavor under scrutiny. Koop sent additional Spring Energy gels, Canaberry (named after professional ultrarunner Sage Canaday) and Hill Aid, to the lab for testing. The results indicated that both of these flavors also contain fewer calories than stated on their nutrition labels.

The lab results showed that the batch of Canaberry that was tested contains 10g of carbs (versus the stated 17g), and the Hill Aid sample contains 10g of carbs (versus the stated 20g).

Koop also paid for Gu Chocolate Outrage to be tested. The results were consistent with the nutrition facts. All three of these reports can also be found on Koop’s website.

These vast discrepancies between Spring Energy’s reported nutrition facts and the lab results raise the question: which gels can be trusted?

According to the U.S. Food and Drug Association (FDA), most running gels fall under the category of “dietary supplements”, which don’t have to be approved before being sold. However, the FDA requires that all dietary supplements have nutrition information clearly marked on a product’s packaging (including serving size, number of servings, and ingredients) and periodically inspects manufacturing facilities to confirm that products meet the labeling requirements. The FDA also reviews product labels for accuracy.

“Dietary supplements are regulated by the FDA, but much of our role begins after products enter the marketplace. In fact, in many cases, companies can produce and sell dietary supplements without even notifying the FDA,” the FDA states on their website.

The FDA allows nutrition labels to have an inaccuracy margin of up to 20 percent—for reference, based on multiple lab results, Awesome Sauce’s caloric content is about 57 percent less than what the label says.

Sports psychologist and ultrarunning coach Krista Austin works with some of the top endurance athletes in the world, and is best known for training Meb Keflezighi to  his 2009 New York City Marathon win. She recommends several products out on the market to her ultrarunner athletes, as well as suggestions that might work with a person’s individual plan. Typically, she suggests that athletes rotate gel flavors to avoid flavor fatigue, which can impact an athlete mentally and derail performance. So if a certain brand is proven to work well for an athlete, she says, use a variety of flavors.

“I usually use high molecular weight carbohydrates, but the thing is, they’re not as sweet as other sports nutrition products out there,” says Austin, who owns a consulting business providing sport performance services to Olympic and professional athletes as well as military and industry personnel. “So what we’ll do is we might throw in another gel like the Awesome Sauce to help give them that sweet component. It’s just in their arsenal.”

She says, in general, her athletes who have consumed Awesome Sauce have had positive experiences, but that because these gels were just one part of the fuel plan, that muddies the waters a bit. In addition, the potential lower calorie count of this gel may make it easier to digest. However, Austin recalls that one of her clients was taking in one Spring Energy gel (multiple flavors) every hour in her ultra, but found herself so hungry that she needed to eat a lot of the food provided at aid stations on the course, too.

“She was a smaller ultrarunner, and I thought it was interesting that she was taking in all these calories,” Austin says. “She was using Spring Energy gels, and I now I’m thinking, ‘Maybe this is why she needed all the additional food on the course, too, because she wasn’t getting what we thought she was.’”

Ultramarathon dietician Julie Shobe is surprised and disappointed in the news about Awesome Sauce. “My clients and myself bank on the efficiency of the gel being easy and light to carry,” she says. “Underfueling within a long run can create acute symptoms like low energy, nausea, or brain fog. Ultrarunners find themselves in dangerous situations on long runs and races, and are often in remote areas, so unintentionally underfueling could have negative consequences.”

Austin says runners can still rely on information they’re receiving about endurance fuel, but that it’s always possible there are, as Spring Energy suggests, bad batches. She’s leaning toward this being the reason for the nutritional inaccuracies (keeping an open mind that more information can come out) because she’s had experiences with bad batches of gels in the past, where the product tasted off and she brought it to the attention of the brand, who confirmed it was an error on their part.

By May 30, Spring Energy had removed Awesome Sauce from its website, although it can still be purchased in the All Inclusive and Vegan Spring sampler packs. There, Awesome Sauce is described as, “our best-seller, has been created for all carb lovers who want to fuel in a healthy way, with wholesome products free of added sugars!”

Nashville Running Company owner Lee Wilson has made the decision to take Awesome Sauce,  Canaberry, and Hill Aid off store shelves. “It came down to the integrity of it,” Wilson says. “After the other flavors came out with the test results, we decided we can’t sell it.”

Nashville Running Company crew member Eric May added that this whole ordeal is disappointing, especially because the gel was so popular in the community.

“We used to have people come in when we got shipments and walk out with boxes of them,” May says. “It’s a bummer.”

He adds that a few customers have remarked that they still really enjoy Awesome Sauce and will keep using it.

“How a company reacts to the issue tells you a lot about them, and the fact that they’ve taken down their product, it means they’re probably doing their homework to see what’s going on,” Austin says. “I would say, give them a chance to rectify the situation.”

Sabrina Stanley, a pro ultrarunner from Silverton, Colorado, has used Awesome Sauce frequently in the past, but says she stopped eating it when she felt she was taking in three times what she should be consuming to keep hunger at bay. She adds that though it’s a huge disappointment that athletes thought they were buying a gel under the impression it was a different product, the company is the only party at fault.

“Professional athletes aren’t responsible for making sure the nutrition label is correct,” Stanley says. “They are often sub-contracted to give opinions and help promote a product in hopes of making a few extra dollar to continue doing what they love. They aren’t in the lab developing the product and writing the nutrition label, like the consumers, they are trusting the hired them to do their due diligence.”

On May 29, Spring Energy released an official statement on its Instagram, with Nazarewicz saying they’ve identified weaknesses in the manufacturing process, and that only some batches were accidentally made with varying nutritional values. Nazarewicz apologized and stated Spring Energy is introducing changes to its process and hopes to continue its mission toward making real food performance products.

“Spring Energy has admitted to inconsistencies in their product and also said in a recent IG post this was not intentional or malicious,” Shobe says. “However, to be this far off from your stated nutrition label deserves some major inspection. The whole thing made me question not only the integrity of their products but the nutritional labels of other products. Why, as a dietician, didn’t I become more suspicious of Awesome Sauce in the first place?”

Ethiopia’s Fotyеn Tesfay Haylu delivered one of the most remarkable women’s half-marathon performances ever seen on American soil on Sunday, powering to a commanding victory at the 2026 Buenos Aires Half Marathon in Argentina in 1:03:57.

Running with exceptional confidence and strength, Tesfay took control of the race and produced a superb solo performance to rewrite the event record. Her breathtaking run also carried historic significance, as she became the first woman to break the 64-minute barrier for the half marathon in the Americas, producing what is being celebrated as the fastest women’s half-marathon performance ever recorded on the continent.

The Ethiopian star was in a class of her own, crossing the finish line more than a minute clear of Turkey’s Nevin Can, who finished second in 1:05:06. Another Turkish athlete, Selin Can, completed the podium in third place with 1:05:11, as the leading trio all produced strong performances on the fast streets of Buenos Aires.

Kenya also featured prominently in the top positions, with Irene Jepchumba Kimais taking fourth in 1:06:04, followed by Sheila Chepkirui in fifth with 1:06:13. Magaret Akidor Ngathike finished sixth in 1:06:46, while fellow Kenyan Deborah Samum claimed seventh place in 1:08:32.

Brazil’s Nubia de Oliveira Silva was eighth in 1:11:13, while Argentina’s Sofia Luna and Dahyana Juarez rounded out the top 10 with times of 1:11:21 and 1:11:28, respectively.

Top 10 Women – 2026 Buenos Aires Half Marathon

1. Fotyеn Tesfay Haylu (Ethiopia) – 1:03:57

2. Nevin Can (Turkey) – 1:05:06

3. Selin Can (Turkey) – 1:05:11

4. Irene Jepchumba Kimais (Kenya) – 1:06:04

5. Sheila Chepkirui (Kenya) – 1:06:13

6. Magaret Akidor Ngathike (Kenya) – 1:06:46

7. Deborah Samum (Kenya) – 1:08:32

8. Nubia de Oliveira Silva (Brazil) – 1:11:13

9. Sofia Luna (Argentina) – 1:11:21

10. Dahyana Juarez (Argentina) – 1:11:28

For Tesfay, it was far more than a race victory. Her 1:03:57 performance was a statement of extraordinary quality, combining speed, endurance and remarkable solo running to produce a landmark result in Buenos Aires. In a race that will be remembered for years to come, the Ethiopian did not simply win—she redefined what was thought possible for women’s half-marathon running in the Americas.

Ethiopia’s Yomif Kejelcha produced one of the most extraordinary performances in road racing history on the streets of Buenos Aires, Argentina, reclaiming the half marathon world record with a sensational 56:51 performance at the 2026 Buenos Aires Half Marathon.

The former world record-holder delivered a breathtaking exhibition of speed and endurance to take 29 seconds off the previous pending mark of 57:20, set by Uganda’s Jacob Kiplimo and takes a huge chunk from his own former official world record. Kejelcha's new performance is pending the standard ratification procedures, but if officially ratified, it will return the world record to the Ethiopian star and mark another remarkable chapter in the evolution of the event. 

Kejelcha's achievement is particularly significant because the 57-minute barrier had already been broken before. Jacob Kiplimo had previously run under 57 minutes, clocking 56:42 that was not ratified demonstrating that the once-unthinkable barrier was possible. Kejelcha, however, has become the second man to run under 57-minute barrier who now returns to the top of the all-time rankings with another historic performance in Buenos Aires.

The Ethiopian's race was remarkable not only for the final time but also for the way he built his performance. He covered the opening five kilometres in 13:44 before reaching 10km in 27:18. Rather than slowing, Kejelcha accelerated through the middle stages, passing 15km in 40:39 and 20km in 54:02 as he continued to push the limits of elite road racing.

By the time he reached the finish line, Kejelcha had completed the race at an extraordinary average pace of approximately 2:42 per kilometre, producing one of the most astonishing sustained efforts ever witnessed in distance running. His stunning run sent a powerful message to the athletics world and further strengthened his status as one of the most formidable distance runners of his generation.

Behind the record-breaking champion, Ethiopia completed a dominant clean sweep of the men's podium. Tadese Worku Gebresilase claimed second place in 59:18, while Bereket Nega Batebo secured third in 1:00:17, giving Ethiopia a memorable one-two-three finish in the Argentine capital.

Kenya’s Jonathan Kipkoech Kamosong finished fourth in 1:00:20, followed by compatriot Simon Maywa in fifth with 1:00:55. Argentina’s Ignacio Erario gave the home supporters plenty to celebrate with an impressive sixth-place finish in 1:00:57, breaking the one-hour barrier in front of an enthusiastic local crowd.

Dillon Kipyeko of Kenya finished seventh in 1:01:07, with Robert Kiprop Koech eighth in 1:02:01. Mexico’s Julio Ortiz Ponce took ninth place in 1:03:17, while Colombia’s Jimmy Gómez completed the top 10 in 1:03:34.

The Buenos Aires Half Marathon will now take its place in the history books as the scene of a truly extraordinary breakthrough. For Kejelcha, this was more than just another victory. It was a spectacular return to the top, reclaiming a world record he had previously held and once again rewriting the limits of the half marathon.

The 56:51 performance remains pending ratification, but Yomif Kejelcha's run has already delivered one of the defining moments in the history of road racing.

Kenya delivered another commanding display of distance-running excellence at the Antrim Coast Half Marathon, with Isaia Lasoi leading a memorable Kenyan clean sweep of the men's podium in a race packed with world-class performances.

Lasoi emerged victorious after a thrilling battle at the front, crossing the finish line in a superb 58:26 setting a new course record. His winning performance underlined his strength and speed over the half-marathon distance, but he was made to work all the way by fellow Kenyan Daniel Mateiko, who finished just three seconds behind in 58:29 after an electrifying duel for the title.

The contest between the two leaders produced one of the standout moments of the race, with both athletes pushing deep into elite territory as they fought for victory. In the end, Lasoi found just enough to secure the win, while Mateiko's narrow defeat highlighted the remarkable depth and quality of Kenya's leading distance runners.

Vincent Kipkorir completed the Kenyan sweep, taking third place in 1:00:38 to ensure that all three places on the podium belonged to Kenyan athletes. Samwel Chebolei added further Kenyan strength to the results, finishing fourth in 1:01:01, while Amos Langat was also among the leading finishers.

The international field featured several prominent names. Australia's Jimmy Whelan produced a strong run, while Ethiopia's Yismaw Dillu featured among the front group. American marathon star Galen Rupp also delivered a notable performance, clocking 1:01:29 in another competitive outing for the experienced distance runner. Former world-class track and road athlete Edward Cheserek was also among the top finishers.

Lasoi's 58:26 victory, however, was the defining performance of the day. Together with Mateiko and Kipkorir, he gave Kenya a perfect podium and another emphatic reminder of the country's extraordinary strength in elite road running.

The Antrim Coast Half Marathon once again provided a fast, competitive stage for some of the world's finest distance runners, but when the decisive moments arrived, it was Kenya that owned the podium.

One of the most iconic milestones in the history of ultramarathon running is drawing closer, with entries for the historic 100th edition of the Comrades Marathon set to open on Tuesday, 25 August 2026.

The Comrades Marathon Association has officially announced a detailed entry process for the 2027 race, which will unfold in three stages and give runners around the world the opportunity to secure their place in what promises to be one of the most significant editions ever held of The Ultimate Human Race.

The announcement followed the official launch of the 2027 Comrades Marathon on Wednesday, 19 August, when the centenary campaign, “The Greatest Story Ever Run,” was unveiled alongside a special logo created exclusively for the landmark 100th edition.

The launch also revealed several major highlights for the Centenary Race. The historic event will take place on Sunday, 13 June 2027, and will be a Down Run, with 28,000 places available. The entry process will include a ballot, while the race will offer a record R8.919 million in prize money. Organisers have also set an ambitious goal of raising R10 million for the Amabeadibeadi charities, adding an important charitable dimension to the centenary celebrations. One of the defining moments of the launch was the unveiling of the special Centenary mark, created to commemorate this extraordinary milestone in the history of the race.

The entry process begins on 25 August at 10:00 a.m. SAST, when entries open for Green Number runners, Yellow Number runners and Amabeadibeadi charity entrants.

The next phase follows on 2 September at 10:00 a.m. SAST, when entries open for Comrades Marathon Association members. This window will remain open for 72 hours or until the available entry allocation is filled, with places offered on a strictly first-come, first-served basis.

For general entrants, the process will move to a ballot system. General entries open on 9 September at 10:00 a.m. SAST, with runners able to enter the ballot until it closes on 22 September at 4:30 p.m. SAST. The ballot draw is then scheduled to take place on 23 September.

Several other crucial dates will shape the road to the historic race. The substitution period will run from 15 to 31 March 2027, while 3 May 2027 is the final deadline for runners to submit their qualifying performances, seeding information and other required entry details.

To qualify for the 2027 Comrades Marathon, runners must complete a 42.2km marathon in under five hours between 15 June 2026 and 3 May 2027.

The journey will finally culminate on Sunday, 13 June 2027, when thousands of runners are expected to line up for the historic 100th edition of the Comrades Marathon.

The 2027 race will represent a remarkable moment for the legendary South African ultramarathon. For more than a century, the Comrades Marathon has captured the imagination of runners and spectators with its extraordinary test of endurance, determination and human spirit. Its centenary edition will celebrate the generations of athletes who have faced its demanding roads, conquered its challenges and helped build one of the world's most respected endurance events.

For runners dreaming of becoming part of this historic occasion, the road to Comrades 2027 is now clearly marked. From the opening of entries in August 2026 to race day in June 2027, every deadline will matter.

The Greatest Story Ever Run is preparing for its most historic chapter yet.

American sprint standout Sam Blaskowski is taking steps toward an international future with Poland after uncovering a powerful connection to his family's ancestral homeland.

The 23-year-old sprinter, who has established himself as one of the fastest Americans of his generation with a personal best of 9.89 seconds in the 100 metres, has begun the process of obtaining Polish citizenship with the aim of eventually representing Poland in international competition.

Blaskowski's connection to the country traces back through his great-grandparents, Franciszek and Julian Błaszkowski, who emigrated from Poland to the United States in 1905. Their journey more than a century ago has now opened an unexpected new chapter for their descendant, whose athletic ambitions could soon carry the Błaszkowski name back onto the international stage under Polish colours.

The sprinter has already received support from the Polish Athletics Association as he works through the citizenship and eligibility process. Should his transfer of allegiance be completed, Blaskowski could become a significant addition to Poland's sprint programme.

His credentials certainly make the prospect an exciting one. In addition to his sub-10-second speed over 100 metres, Blaskowski owns a personal best of 19.93 seconds in the 200 metres, demonstrating the kind of versatility that could prove valuable both individually and in Poland's 4x100m relay squad.

For Blaskowski, however, the move is about more than simply changing national colours. It represents an opportunity to reconnect with his family's heritage while pursuing his ambitions at the highest level of the sport.

With his sights set on becoming part of Poland's international sprint team and competing for relay medals, Blaskowski's journey from discovering his Polish roots to potentially representing the country of his ancestors could become one of the most fascinating allegiance stories in world athletics.

A century after Franciszek and Julian Błaszkowski left Poland for America, their family's story may now be coming full circle—this time at full sprint.
