Experts break down which type of runner is most likely to benefit from tests including a gait analysis, VO2 max, and more.

Running itself is pretty basic—in the best of ways. All you really need is a pair of running shoes to get started. Of course, additional gear can be helpful, not to mention fun to test out and use to boost performance. Investing in certain fitness tests and assessments can also up the fun factor and give you an edge for training and race-day success. 

These days, you can find a ton of options in this realm, which can feel overwhelming, but experts caution against getting too caught up in the hype. 

“Information and knowledge is a good thing, but sometimes there can be a little bit too much,” says James Robinson, M.D., sports medicine physician at Hospital for Special Surgery. He says that if you’re not having problems (like injuries or pain) and you’re hitting reasonable running goals, you probably don’t *need* any type of fitness test. 

One exception: Keep up with your yearly physicals (during which you may have some blood work done) as a baseline. From there, your doctor may also suggest other specific tests (like a DEXA scan, which looks at bone density, for those with osteopenia or a history of broken bones). 

That said, keep reading for what runners should know about some of the most popular fitness lab tests out there right now, how each can support your goals, and which type of runner is more likely to benefit from investing in each one. 

If you’re chronically injured or looking to improve efficiency...

Consider a gait analysis

A gait analysis—which involves being recorded from different angles while running on a treadmill to look at form, including foot strike and body alignment—is especially useful for runners with chronic injuries like shin splints, patellofemoral pain, or IT band issues, says Robinson. 

“The gait analysis can show things in your running mechanics that are making you more prone to injuries and especially certain types of injuries,” says Robinson. This analysis may also ID weaknesses or muscle imbalances and things like overstriding, overpronating, or a low cadence.

Runners looking to improve efficiency may also benefit from this test. “There can be ways to improve your biomechanics to improve your running efficiency,” like working on optimizing hip extension, which is important for minimizing vertical excursion (or too much up and down movement rather than straight ahead).

N’Namdi Nelson, C.S.C.S., an exercise physiologist at NYU’s Sports Performance Center adds that beginners can benefit from a gait analysis: “The activity you’re going to be doing is running, so why not do a running analysis to assess your biomechanics to see exactly what's going on in your gait, and identify things that you may be doing incorrectly and ways that you can improve it?” This will not only set you up for success in the sport of running in terms of performance, but help you avoid injuries before they show up in your stride.

Where to get it: Running labs like at universities and medical centers or at a local physical therapy clinic

Typical cost: Starting at about $150 (or free with your physical therapy appointment, depending on insurance)

If you’re new to running…

Consider a functional movement screening (FMS)

When doing a functional movement screen, a coach or trainer will typically put you through movements (e.g. a single-leg squat, push-up, and step-over) and watch how your body moves. If your hip drops to one side or your knees cave in on that squat, for example, that could indicate weakness in your core stability, Robinson says, which could affect your injury risk in running. The facilitator will then give you specific exercise recommendations to strengthen those weaknesses. 

Nelson recommends the FMS for beginners in particular. “It’s going to give us more information as to what’s going on in the body,” he says. “So for example, if we see weakness in certain muscles or a decrease in flexibility in certain joint ranges, then we can try to get ahead of it and try to correct it, decreasing your chances of sustaining some type of running-related injury.”

Where to get it: Some places, like NYU, HSS, and the Columbia RunLab, offer running analyses which combine a gait analysis on a treadmill with a movement screen like the FMS so it’s one stop shopping. Nelson says that having information from both of these inputs—the gait analysis and FMS—can be helpful when making correlations. 

You can also often get an FMS at a gym as part of an initial training evaluation, and it can be useful on its own. (If you’re choosing between a gait analysis and an FMS, Robinson argues the former is more beneficial as it’s more specific to runners.) 

Typical cost: Included in the above services, with rates changing depending on insurance and/or location

If you’re more experienced and/or get sidelined by cramps…

Consider a metabolic profile test

This type of test typically includes a VO2 max test, lactate threshold evaluation, and metabolic efficiency testing. It involves a finger stick capillary blood test, as well as running on a treadmill at increasing intensity with a mask on to measure how much oxygen you’re consuming, as well as CO2 output and heart rate. 

VO2 max measures your aerobic capacity. It can give you a sense of your cardiovascular fitness, which can be helpful as a benchmark to try to improve (often via short, intense intervals). 

This test can also help you determine your max heart rate, and training zones based on that

“Lactate threshold is basically the point at which your body starts to go from aerobic to anaerobic and starts to really ramp up its levels of lactate,” says Robinson. “The lactate threshold basically tells a runner the pace at which they could run a short distance, like a 5K or 10K, which can be useful when you’re talking about training paces.” 

Importantly, lactate threshold is something you can train and improve, Robinson adds. Knowing your threshold allows you to train in the proper zones to increase it. For example, if your lactate threshold is nine minutes per mile, then training with runs at that pace could help to improve that, Robinson says. (And then if you repeated this test months later, you can see if it improves.)

As for metabolic efficiency, Robinson says this can help you strategize fueling for long races—and it’s also trainable. This test profile measures how many calories you use per hour and the breakdown of fat versus carbohydrate at various exercise intensities. 

“We have a lot of fat stores in our body, but our body has very limited carbohydrate stores,” he says. So, if the test reveals that you’re using mostly carbs for long runs, for example, you’ll run out of fuel quickly and knowing this would help you ID exactly how much nutrition you need to bring along.

Robinson says this test is most useful for runners trying to improve efficiency and pace. For example, if you want to run a sub-four-hour marathon, this test can be useful to one, see if you’re able to achieve that goal at your current fitness level, and if not, figure out which zones to train to get there. 

The test can also be useful for those who deal with cramping when they run. “Usually cramps are a fueling issue more so than a true dehydration issue,” says Robinson. “So the metabolic profile can be useful for fueling to see why someone might be cramping, or for someone that hits a wall at mile 20 or 21 in the marathon, that could be a fueling issue, and the metabolic profile can definitely help clue you into strategies to help.” 

Where to get it: At NYU, this test is called the “Sports Performance” evaluation and includes a gait analysis, stability and mobility screen, and VO2 max, with the option to add lactate threshold testing. At HSS, it’s Metabolic Testing and includes all of the metrics (VO2 max, lactate threshold, metabolic efficiency, and also running economy). You also may be able to find similar tests at other universities, medical centers, and running labs. 

If you want to DIY…

Use your wearable data

Robinson acknowledges that many wearables now provide lots of info that you’d get as part of a formal gait analysis, like cadence, vertical oscillation, and stride length, in addition to metrics like VO2 max. “They’re pretty accurate now,” he says, adding that they can be more accessible and less expensive (assuming you’ve already paid for the wearable) than additional testing. 

Still, sometimes people need help with interpretation of this data and they don’t know what to do with it on their own. “Seeing an exercise physiologist or a running coach could help them interpret some of the data,” he says.

Typical cost: Free (after the cost of a wearable, which typically starts around $200) 

If you’re into lots of data and optimizing health…

Consider a blood panel

As long as you pass your yearly physical, additional blood work probably won’t tell you much more about your running performance, according to Nelson. “You can identify some nutritional deficiencies and things like that that may affect your performance, but those things may also be highlighted in your yearly physical,” he adds. 

However, for those really into data and optimization of health and performance, a full blood panel might be helpful, so long as you know what to do with the information (or have someone to interpret the results). This additional screen may look into nutritional biomarkers beyond your typical blood test at a physical, like omega-3 levels, electrolytes like calcium and magnesium, and many other health-related metrics that are related to heart health, immune regulation, and more.

The one biomarker both experts agree is wise to get tested for all runners is vitamin D. “I do recommend that runners get their vitamin D checked regularly because if you are low in vitamin D, then that can put you at risk for bone injuries such as stress fractures, and vitamin D deficiency is extremely common, especially in places where you don’t get as much sunlight,” says Robinson. 

Other than that, if you’re having specific issues or have concerns about your overall health, consult with your doctor to see what biomarkers, if any, should be tested. 

Where to get it: Your doctor should be able to run additional lab tests if you have a medical need for them, but you can also try a direct-to-consumer service like Function or Inside Tracker.

Typical cost: Free one time a year with most insurance providers (for the basics), but around $500 for the DTC services. 

The prospect of seeing one of athletics' biggest stars back on the track is growing stronger, with Jakob Ingebrigtsen reportedly targeting a return to competition later this summer following his recovery from Achilles tendon surgery.

According to comments made by his agent, Daniel Wessfeldt, in an interview with Norwegian media, the double Olympic champion could make his long-awaited comeback at one of three major European meetings in July. The leading options under consideration are the Monaco Diamond League on July 10, the Hungarian Athletics Grand Prix on July 14, and the London Diamond League on July 18.

For athletics fans, the possibility of Ingebrigtsen lining up in London would add another layer of excitement to an already highly anticipated Diamond League meeting. The Norwegian middle-distance sensation has become one of the sport's most dominant figures in recent years, collecting Olympic, world and European titles while consistently rewriting record books.

His 2026 campaign was put on hold after he underwent surgery on his Achilles tendon earlier this year, forcing him to focus on rehabilitation rather than competition. Since then, questions have surrounded when the 24-year-old would be ready to return to racing.

The latest update suggests that decision will largely depend on how his training progresses over the coming weeks. If recovery continues according to plan, July could mark the beginning of his return to elite competition ahead of the latter stages of the season.

A comeback at either Monaco, Budapest or London would immediately place Ingebrigtsen back among the sport's biggest storylines. Each meeting is renowned for producing world-class performances, and any appearance by the Norwegian would attract significant attention from fans eager to see how quickly he can regain top form after his injury setback.

While no final decision has been confirmed, the signs are increasingly positive. After months away from competition, Jakob Ingebrigtsen appears to be edging closer to a return, with London's Diamond League meeting emerging as one of the most intriguing possibilities on his road back to the track.

Should his recovery continue smoothly, athletics could soon welcome back one of its brightest and most influential stars.

What should have been the defining moment of Emad Bashir-Mohammed's young running career instead turned into one of the most talked-about controversies in American road racing this year.

The 23-year-old crossed the finish line first in the men's citizen's race at the prestigious Bolder Boulder 10K on Memorial Day in Colorado, stopping the clock at an impressive 29:50. His performance was not only a commanding victory but also one of the fastest winning times ever recorded in the event's long and celebrated history. Bashir-Mohammed finished eight seconds clear of his nearest challenger and appeared to have secured a breakthrough triumph.

For nearly two hours, he was the undisputed winner.

Then everything changed.

Race officials announced that Bashir-Mohammed had been disqualified after determining that he had started in the wrong wave. According to Bolder Boulder regulations, he had been assigned to the AA wave but lined up with the faster A wave, which began earlier. Event rules allow runners to move backward into a slower wave, but prohibit athletes from advancing into a faster one.

As a result, Bashir-Mohammed's victory was erased from the record books.

The citizen's title was subsequently awarded to Nickolas Scudder, who crossed the line second in 29:58. The promotion handed Scudder back-to-back citizen's race victories, while Bashir-Mohammed was left to grapple with the disappointment of losing a win he believed he had earned on the road.

The disqualification has since ignited widespread debate across the running community.

Bashir-Mohammed maintains that he did not intentionally violate the rules. He claims that after collecting his AA bib, he spoke with race personnel and was permitted to start with the A wave after presenting evidence of his recent performances. In a statement shared after the race, he expressed frustration over the decision, arguing that his goal was simply to compete against the strongest field available and produce the fastest time possible.

Race organizers, however, stood firmly behind their ruling. Officials stated that wave-assignment regulations are clearly communicated in pre-race information and reiterated during packet collection. They also noted that hundreds of participants are disqualified each year for moving into faster start groups, emphasizing that consistent enforcement is necessary to maintain fairness for all competitors.

The incident has divided opinion among runners and fans alike. Some believe the rules must be applied equally regardless of an athlete's finishing position, arguing that wave assignments are a fundamental part of race organization. Others feel the punishment is harsh, particularly if Bashir-Mohammed genuinely received approval to move up before the start.

What remains undisputed is the quality of his performance. On the roads of Boulder, Bashir-Mohammed demonstrated the fitness and speed required to outrun the field by a significant margin. Yet in road racing, crossing the finish line first is only part of the equation. Compliance with race regulations carries equal weight.

For Bashir-Mohammed, the day will be remembered as a painful lesson in the fine margins that can define elite competition. A remarkable run delivered a memorable victory, but a dispute over wave placement ultimately overshadowed the achievement, leaving behind a controversy that continues to fuel discussion throughout the running world.

A fast race, a costly administrative error, and a debate that may linger long after the finish-line tape has been packed away.

The men's 100 metres at the 2026 Rome Diamond League is shaping up to be one of the most anticipated sprint races of the season, with an exceptional field featuring some of the fastest men in the world.

Scheduled for Thursday, June 4, at the iconic Stadio Olimpico in Rome, the race will bring together reigning stars, established champions and emerging talents in a contest that promises fireworks from the moment the gun goes off.

Kenya's Ferdinand Omanyala headlines a world-class lineup that includes American sprint sensation Noah Lyles, Botswana's Olympic champion Letsile Tebogo, Jamaica's explosive Ackeem Blake, South Africa's ever-consistent Akani Simbine and Italy's hometown hero Lamont Marcell Jacobs. With personal bests ranging from 9.77 to 9.97 seconds, the field is packed with athletes capable of producing something special on the Diamond League stage.

Omanyala, the African record holder with a blistering personal best of 9.77 seconds, arrives in Rome eager to continue his strong early-season form and prove he can challenge the very best on the global circuit. The Kenyan star has built a reputation as one of the fastest starters in world sprinting and will be looking to make a statement against an elite field.

Standing in his way is world champion Noah Lyles, whose personal best of 9.79 seconds places him among the fastest athletes in history. The American remains one of the sport's biggest attractions and will be determined to add another Diamond League victory to his impressive résumé.

The race also marks a major test for Olympic champion Letsile Tebogo. The Botswanan star has rapidly become one of athletics' most exciting talents, while Ackeem Blake continues to establish himself as a serious contender on the international sprint scene.

Adding further intrigue is the presence of Italy's Lamont Marcell Jacobs. Competing on home soil, the Tokyo Olympic champion will enjoy passionate local support as he seeks to deliver a memorable performance in front of the Roman crowd.

South Africa's Akani Simbine, Cameroon's Emmanuel Eseme, Great Britain's Jeremiah Azu and rising American talent Jordan Anthony complete a field that boasts remarkable depth and quality.

Audrey Werro announced her arrival as one of the early stars of the 2026 outdoor season with a commanding victory in the women’s 800 metres at the Rabat Diamond League, producing a performance that exceeded even her own expectations.

The Swiss middle-distance talent surged to victory in a brilliant 1:56.56, breaking the meeting record and delivering one of the fastest times recorded worldwide this season. In a race packed with quality, Werro displayed exceptional composure, confidence, and finishing strength to separate herself from the field and stamp her authority on the event.

What made the performance even more remarkable was the athlete's surprise at the level she had already reached so early in the campaign.

"I was not expecting such a strong start to the season," Werro admitted after the race.

The race unfolded at a relentless pace, but Werro remained perfectly positioned throughout. As the athletes approached the bell lap, she glanced at the clock and immediately sensed something special was within reach.

"When I saw the time at the bell, I felt really confident," she said. "I'm really happy with the Meeting Record and looking forward to the rest of the season."

Her confidence proved justified. Maintaining her rhythm over the final 400 metres, Werro powered down the home straight to secure the victory and rewrite the Rabat meeting record books in the process.

The performance sends an early warning to her rivals ahead of a season that promises major championships and high-profile Diamond League battles. Beyond the record-breaking time, Werro's display highlighted her growing maturity as a racer, combining tactical awareness with impressive speed and endurance.

With the outdoor season only beginning, the 1:56.56 clocking suggests that even faster times could be on the horizon. If Rabat is any indication, Audrey Werro may be poised for the biggest season of her career.

Her emphatic victory in Morocco was more than just another Diamond League win—it was a statement of intent from an athlete determined to challenge the world's best throughout 2026.

The city of Boston is set to welcome back one of its most celebrated champions as Kenya’s Sharon Lokedi headlines a world-class field for the 2026 B.A.A. 10K presented by Mass General Brigham Cancer Institute on June 21.

Fresh from another remarkable victory at the Boston Marathon in April, Lokedi returns to the streets of Boston and Cambridge carrying both momentum and confidence as she aims to defend the title she captured in dominant fashion last year.

The two-time Boston Marathon champion has developed a special connection with the historic race city. In 2025, she produced a course-record performance of 2:17:22 to win the Boston Marathon before returning this year to claim another victory in 2:18:51, the second-fastest winning time in the event’s storied history. Her success has cemented her status as one of the premier road runners in the world.

Lokedi will be making her first competitive appearance since her marathon triumph and arrives as the reigning B.A.A. 10K champion after clocking 31:39 over the challenging 6.2-mile course in 2025.

“Boston has become a very special place for me,” Lokedi said ahead of the race. “The atmosphere created by the fans and the community is unlike anywhere else. I’m excited to return and give everything I have to defend my title.”

The women’s race promises to be highly competitive. American Olympian Rachel Smith, who finished second at the Boston 5K in April, leads the domestic challenge. Kenya’s strong contingent includes African 10,000m champion Gladys Kwamboka, former B.A.A. 10K runner-up Stacy Ndiwa, and experienced road racer Viola Cheptoo. British Olympian Jessica Warner-Judd adds further international depth to a field packed with proven performers.

The men’s race is equally impressive, featuring elite athletes from 13 nations.

Ethiopia’s Dawit Seare enters as one of the leading contenders after capturing the 2025 Boston 5K title and bringing the fastest 10K personal best in the field at 27:21. Kenya will be represented by an accomplished group led by Alexander Mutiso, winner of the 2024 London Marathon and runner-up at last year’s New York City Marathon.

Patrick Kiprop also arrives in outstanding form after securing victory at the prestigious BolderBoulder 10K on Memorial Day, while Alex Masai returns looking to continue his strong record in Boston. Masai recently finished ninth at the Boston Marathon and has earned three top-ten finishes at the B.A.A. 10K.

Among the international stars making their mark is South Africa’s Adriaan Wildschutt, who makes his race debut after an impressive season highlighted by victory at the NYC Half Marathon in 59:30. Ethiopia’s Olympic bronze medallist Hagos Gebrhiwet adds further quality to the field, bringing a wealth of championship experience and previous success in Boston.

Canadian national 10K champion Andrew Alexander, two-time U.S. Olympian Hillary Bor, marathon standout Ryan Ford, and reigning USA 25K champion Andrew Colley complete a field stacked with talent and depth.

With defending champions, Olympic finalists, national champions and rising stars all converging on Boston, the 2026 B.A.A. 10K is shaping up to be one of the most competitive editions in recent memory. For Sharon Lokedi, however, the mission is simple: return to the city where she has repeatedly excelled and add another memorable chapter to her growing Boston legacy.
