Running News Daily

Right now in the fitness community, the hottest topic is Zone 2 training.

Everywhere you look, both coaches and runners are extolling the benefits of running at a Zone 2 effort, while advising runners to be wary of running too hard on easy days.

Make no mistake: there are great reasons for running most of your mileage at an easy effort around Zone 2. No coach worth her salt will tell runners that easy running isn't advantageous. In fact, a lot of easy running is the key to racing faster and building a strong body that's resilient against injuries.

But with all this focus on Zone 2, are we ignoring other zones? What about Zone 1? Or what about Zone 3 (which seems to have become the boogeyman of running efforts)? Despite the baggage of Zone 3, and most athletes ignoring Zone 1, these zones still have value.

In fact, every zone has a place in a well-designed training program. Let's get into the weeds, explore the nuance, and discover each shade of gray about zone training.

What is Zone 2 Running?

Zone 2 running is best defined as easy running where you're still able to hold a conversation with a friend. The effort usually corresponds to about 60-70 percent of maximum heart rate.

This zone is part of the 5-zone system:

Zone 2 is often considered the lowest intensity that produces meaningful training adaptations. It's receiving a lot of attention in the running community because it has a lot of benefits with very little risk of over-training or injury. But this is not new. Runners have been married to the idea of easy running since the 1970s, when US marathoner Bill Rodgers was winning major marathons while running up to 180 miles per week-nearly all at an easy effort.

We've called long runs LSD ("Long Slow Distance"), short runs "recovery jogs," and bemoaned our training partners for not running at "conversational pace." In Boulder, Colorado, there's a weekly "fun run" at such an easy effort it's called "soft hour."

There's no denying that Zone 2 is a key pillar of any endurance runner's training-in fact, it's likely the most important intensity zone for every runner-but that doesn't mean it's the only actor in the play.

Runners know and understand the value of easy, comfortable running. It's just currently being rebranded into something new called "Zone 2 training" (just like, a decade ago, we heard all about High Intensity Interval Training-or hard track workouts).

Zone 2 is Just One Piece of the Puzzle

There's no denying that Zone 2 is a key pillar of any endurance runner's training-in fact, it's likely the most important intensity zone for every runner-but that doesn't mean it's the only actor in the play. While it's vital, it's just one piece of the puzzle.

Zone 1 running can be enormously helpful for base building, especially with longer efforts that last multiple hours. A four-plus hour fast hike at altitude up a mountain is a good example of beneficial Zone 1 training.

However, Zone 1 isn't as productive at producing endurance adaptations, so it's usually reserved for cross-training, very long efforts, or just parts of certain runs (where most of the effort is Zone 2). A good example is a short recovery run where the first 10 minutes might be at a Zone 1 effort before gradually transitioning to a Zone 2 effort.

And while Zone 3 is often presented as a "danger zone" or the "gray zone" of training, it also has its place. High-level, competitive athletes have the talent to spend more time during an easy run at these moderate intensities. And beginners who are running low mileage can also do a fair amount of Zone 3 running because their volume is low, and they likely won't make as many adaptations without it.

Just be careful with too much Zone 3 running: if more than 40-50 percent of your mileage is at this intensity, it presents a higher injury risk due to additional mechanical stress and less recovery due to higher intensities.

Of course, any performance-oriented runner with goals of running a certain finish time will want to spend time in both Zones 4 and 5, too, which we can consider "workout zones." Race paces of 10K and faster fall into these zones and can be used for structured workouts for approximately 15-20 percent of total weekly volume.

An example week with mileage levels, workouts, and zones illustrates this concept:

In this example, the athlete is running 80 percent of their total weekly volume at a Zone 1 or Zone 2 effort, 10 percent of their effort in Zone 3, and 10 percent in Zone 5.

As we think about the complete training program over the course of a season, we can see that many intensities (like Zone 2) will remain constant throughout the season. Some intensities will have a stronger presence during the base phase, like Zone 1, while others will be prioritized late in the season (like Zone 5).

Just like a delicious soup, every ingredient has its place.

The Bottom Line

Clearly, I'm a Zone 2 stan. It's an integral intensity zone for any runner, whether you're a professional track and field athlete, frequent half marathoner, or a first-time ultramarathoner. If I was forced to choose the single-most important zone for running, I'd choose Zone 2.

But it's not the only party in town. Every runner should strive to be a well-rounded athlete who's capable at every intensity zone. Simply put: Zones 1-3 build capacity while Zones 4 and 5 sharpen your existing fitness. Any good training program should include a healthy mix of all zones because these energy systems all contribute to an athlete's ability.

Ultimately, good runners have range at a variety of distances because they don't ignore any zones or over-prioritize a specific zone. And that range-the ability to run well at the 5K, half-marathon, and ultra distances-is a testament to preparing every energy system during training.

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.

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.
