Run your intervals at the right speeds to make sure you’re getting the most out of each effort.

Getting faster doesn’t happen overnight. To run a faster marathon, for example, you have to first pick up the pace during short segments. When those short segments start to feel easy, you can start extending the amount of time you spend at that pace—eventually to as long as 26.2 miles.

That’s the benefit of interval training, a.k.a doing short, high-intensity efforts followed by low-intensity rest or recovery. With this approach, you can clock more high-intensity effort overall than you would during a steady-state run.

Imagine running your fastest mile pace for one mile—you might make it, but collapse at the end. Now, think about running your fastest mile pace for just 400 meters (about one quarter of that mile), followed by a two-minute recovery. You’d likely be able to repeat that six times, which adds up to a mile and a half of quality effort—something that you might not be able to sustain in one go. 

So, if you’re looking to get faster in any distance, intervals are a key workout to have on your training plan—and to maximize the benefits of these speed sessions, you have to find the right pace for you.

Why Interval Runs Need a Place on Your Training Plan

On a physiological level, intervals improve your body’s oxygen uptake abilities (a.k.a. your VO2 max), according to a 2015 study published in the journal Sports Medicine, so your working muscles can use that oxygen more efficiently and running will feel easier at a given intensity level. 

Interval training also leads to greater mitochondrial adaptations compared to continuous training, 2017 research published in the Journal of Physiology found. Your mitochondria—the powerhouses of your cells—produce aerobic energy, which powers the majority of endurance running.

Intervals are also proven to make you faster over time: Trail runners who did interval training for six weeks ran 5.7 percent faster in a 3,000-meter track test in a 2018 study published in the Journal of Strength and Conditioning Research. As your body gets used to maintaining faster paces for shorter periods, holding that pace for longer efforts will start to feel easier. 

But not all intervals are created equally. Short intervals help you develop muscular strength and power, while longer intervals train your body to better buffer lactic acid, so you tire less easily, explains Danny Mackey, head coach of the Brooks Beasts, one of America’s premier middle-distance track teams. Treating every interval like an all-out sprint can tank your workout from the first rep. On the other hand, figuring out how to properly pace a speed workout can feel intimidating. These tips will help you find your footing.

How to Figure Out Your Interval Run Pace

In general, the shorter the interval, the faster your pace (the same way you’d run a 5K faster than a marathon). 

Many training plans use race paces as reference points for intervals. For shorter intervals, you might aim for mile or 5K pace, while longer intervals call for half marathon or marathon pace. If you’ve raced those distances, that’s easy enough to figure you out. You can also pull your average mile pace for any recent race distance and then use a pace calculator to determine your other race paces.

But if you’ve never raced, that’s okay! “The talk test is a good gauge for new runners with no time history,” says Marnie Kunz, a USATF- and RRCA-certified run coach, NASM-certified trainer, and founder of Runstreet. “Intervals should be hard enough that you can’t carry on a conversation, while your recovery efforts should be at a conversational pace.” 

When you’re ready to get more specific with your interval pacing, you can do a time trial or benchmark workout, says Kunz. It’s basically like doing a race minus the race environment. During this type of run, you choose a distance—say, a mile—and then attempt to run it as fast as you can. Then, you can use that pace to determine interval paces.

Reminder: Those race or benchmark paces are a measure of your current fitness. So if you’re looking to hit a goal pace in a certain race, that’s your starting point, says Mackey. “You start where you’re at, and [throughout training] you’ll start noticing that hitting that pace feels easier,” he says. That’s when you start going faster.

That said, it’s a lot easier to run a 400- or 800-meter effort at your 5K pace than a whole 5K—so you can set a goal pace at which you run your intervals that’s a little faster than your average time, says Kunz. For example, if your current 5K personal best is a 7:15 average pace, your 5K goal pace for intervals may be a 7:00. When those 5K repeats at 7:00 feel less intense, it might be time to extend the length of the intervals for that pace.

How to Actually Stick to Those Interval Paces

The point of intervals is to stay consistent—if you run at an all-out sprint for one interval and then go twice as slow for the others, that pretty much defeats the point of the workout, says Kunz. “The biggest mistake runners make is going out too fast,” she says. “It’s better to start a little slower and get slightly faster with each interval.” That goes for within each interval, too—you want to eeeease into it instead of kicking things off at your top speed and slowing down from there.

FYI, that also applies to recovery periods. How long you recover will depend on the type of workout you’re doing. A general rule of thumb is to recover for half or the same amount of time as the work itself (i.e. 200 or 400 meters after a 400-meter interval). If you’re looking to start each effort as close to 100 percent as possible, your heart rate should come down to under 120, or about 60 percent of your maximum heart rate, during recovery, says Mackey. Shorter recoveries ramp up the intensity of the workout because they don’t give your heart rate time to drop.

To make sure you’re not starting out to fast and giving yourself proper recovery, try these tactics for sticking to your interval run goal pace:

Go off RPE

One of the best ways to stick to your paces is to gauge your rate of perceived exertion, or RPE, on a scale of one to 10. Recovery efforts should fall on the lower end of the scale, between numbers one through three; high-intensity efforts should be closer to seven through 10 (the shorter the interval, the higher it should fall on that scale). 

“If you’re not sure if you’re going hard enough, give it a month and see what you learn about your body,” says Mackey. “It’s uncomfortable to be training at those higher RPEs, but I guarantee you’re not only getting more fit, but you’re going to be able to better handle those more intense efforts.”

Integrate Tech

On the flip side, you can turn to tech to help you stay on pace. Certain running watches—like most Garmins and the Coros Pace 2—actually let you program a workout, including goal paces, in their partner apps. When you sync it to your watch and start running, the watch will beep or buzz during intervals to alert you as to whether you’re going faster or slower than your goal pace.

If you don’t love the idea of looking at your watch during intervals, NURVV running insoles, which use 32 different sensors to capture biometric data, have a Pace Coach feature in the partner app where you can program interval workouts. Then during your workout, you’ll get audio, visual, and haptic (if you have an Apple Watch) coaching based on your cadence and step length measurements to help you hit your target pace. 

It’s very rare that the pros are picking themselves off the track, he adds—which means you shouldn’t feel entirely depleted at the end of an interval session, either. 

The best way to end an interval session is to feel like you’ve got just one or two more reps in the tank, he says. That’s a pretty good indication that you put in the work, but will be ready to hit the ground running again in another 24 to 48 hours. 

Most Olympic marathoners spend their youth focused on running. They join track clubs, compete in national championships, and pursue the sport from an early age.

Julia Mayer’s journey was very different.

Today, Mayer is Austria’s marathon record holder, a multiple national record holder on the roads, and an Olympian. Yet for much of her athletic life, running was not her primary sport.

For 16 years, she played soccer.

Then she discovered something that would change her life.

“I noticed that I was really fast in the fun runs and that it was really, really fun,” Mayer said when reflecting on her transition from soccer to distance running.

What began as curiosity quickly became a passion. She eventually made the bold decision to leave soccer behind and focus entirely on running. It was a move that surprised many people around her, but Mayer believed she had found her true athletic calling.

The decision proved to be the right one.

Within a few years, Mayer developed into one of Europe’s top marathon runners. Her steady improvement carried her from local races to the international stage, where she began rewriting Austria’s record books.

She now holds Austrian records in the marathon, half marathon, and road 10K. Her marathon best of 2:26:08 established her as the fastest female marathoner in Austrian history. Her performances in the half marathon and 10K have further cemented her place among the country’s all-time great distance runners.

Her rise culminated with qualification for the 2024 Olympic Games in Paris.

Competing in the Olympic marathon represented the realization of a dream. On one of the most challenging marathon courses ever used for the Olympics, Mayer ran courageously against the strongest field in the world and finished 55th in her Olympic debut.

Behind the scenes, success has come through extraordinary dedication. During marathon preparation, Mayer trains twice a day and covers approximately 200 kilometers, or 124 miles, each week. The workload demands discipline, patience, and a deep commitment to continuous improvement. 

What makes her story especially inspiring is not simply the records or the Olympic appearance.

It is the fact that she found her greatest talent later than many elite runners.

In a sport where athletes are often identified at a young age, Mayer’s journey serves as a reminder that potential does not always reveal itself early. Sometimes it takes years of experience, a willingness to try something new, and the courage to follow a different path. 

The former soccer player who once chased a ball across a field is now chasing history on the roads of Europe.

And according to those closest to her, her best performances may still be ahead.

For runners of every age and ability, Julia Mayer’s story delivers a powerful lesson: it is never too late to discover what you are capable of.

From soccer player to Olympian, her journey proves that remarkable achievements can begin when least expected.

Megan Keith produced the performance of her career in Oslo on Thursday night, shattering one of Scotland’s longest-standing distance running records and cementing her place among Britain’s greatest female 3000m runners.

The 24-year-old clocked a sensational 8:28.35 over 3000m, breaking the Scottish outdoor record that had stood for nearly four decades. In doing so, Keith eclipsed the previous mark of 8:29.02, set by Scottish legend Yvonne Murray back in 1988, ending a record reign that had lasted 38 years.

Keith’s breakthrough run was more than just a national record. The performance also propelled her to third on the UK outdoor all-time list, placing her behind only two of Britain’s most celebrated distance runners — Paula Radcliffe, who leads the rankings with 8:22.20, and Laura Weightman, whose 8:26.07 remains the second-fastest outdoor mark by a British woman.

The significance of Keith’s achievement is amplified by the calibre of athletes she now joins in the record books. For decades, Murray’s mark stood as one of Scottish athletics’ most untouchable records, surviving generations of elite competitors. Keith has now succeeded where many outstanding runners have fallen short, announcing herself as one of the leading distance talents in British athletics.

Her time also compares favourably with the best performances produced indoors. Olympic medallist Laura Muir ran 8:26.41 indoors in Karlsruhe in 2017, underlining just how exceptional Keith’s outdoor effort in Oslo truly was.

The run continues a remarkable rise for the Scottish star, whose progression over recent seasons has transformed her from a promising prospect into a genuine force on the international stage. Running with confidence and composure against elite competition, Keith demonstrated both the speed and endurance required to challenge the very best in Europe and beyond.

With the World Championship season gathering momentum, Keith’s record-breaking display sends a powerful message. Not only has she etched her name into Scottish athletics history, but she has also established herself as a serious contender in one of the sport’s most competitive events.

In Oslo, Megan Keith did far more than break a record. She ended a 38-year wait, climbed into the upper echelon of British distance running, and delivered a performance that may prove to be a defining moment in her career.

British middle-distance talent Phoebe Gill took another significant step forward in her return to top form, producing a determined victory over 800 metres at the Meeting de Marseille in France on Wednesday.

Competing in challenging, wind-affected conditions, the 19-year-old demonstrated both resilience and composure as she held off a late charge from Switzerland's Veronica Vancardo to secure the win in 2:00.81. Vancardo finished just three hundredths of a second behind in 2:00.84, underlining the fiercely contested nature of the race.

While the margin of victory was narrow, the result represented another encouraging milestone for Gill as she continues to rebuild momentum following her injury setback. The young Briton showed impressive race awareness and strength in the closing stages, maintaining her advantage despite the difficult conditions that made fast running a challenge throughout the evening.

The Marseille triumph adds to a growing body of evidence that Gill is steadily progressing toward her best form. Earlier in her comeback campaign, she clocked 2:01.50 for 800m in Bydgoszcz before demonstrating her versatility with a strong 4:05.53 performance over 1500 metres at the BMC Grand Prix meeting in Trafford.

Those performances have highlighted not only her improving fitness but also her ability to compete across multiple distances as she carefully builds her season. The Marseille victory now provides further confirmation that the European junior star is moving in the right direction.

Gill emerged as one of Britain's most exciting middle-distance prospects through a series of breakthrough performances as a teenager, earning widespread recognition for her fearless racing style and remarkable maturity. Injury temporarily interrupted that upward trajectory, but her recent results suggest she is steadily rediscovering the form that made her one of the sport's brightest young talents.

With each race, the signs of progress become increasingly evident. Winning in difficult conditions and under pressure from a quality field is often a stronger indicator than a fast time alone, and Gill's latest success demonstrated exactly those qualities.

As the summer season gathers pace, the Marseille victory offers another confidence boost for the British teenager, whose return continues to gain momentum. If her recent progression is any indication, Gill could soon find herself back among the leading names on the European middle-distance circuit. 

The NCAA Track and Field Championships delivered a moment few could have predicted as Ja’Kobe Tharp produced one of the most astonishing performances in the history of sprint hurdling, rewriting the record books in spectacular fashion.

Competing in the opening round of the men’s 110-meter hurdles, the Auburn star stunned the athletics world by clocking an incredible 12.75 seconds, becoming the first athlete ever to break the 12.80-second barrier. In doing so, he eclipsed the long-standing world record of 12.80 set by Aries Merritt in 2012, a mark that had stood as one of the sport’s most revered achievements for more than a decade.

What makes Tharp’s breakthrough even more remarkable is the scale of his improvement. Entering the championships, the defending NCAA and U.S. champion had recorded a season-best of 13.05 seconds. Yet under the brightest spotlight, he unleashed a performance that exceeded every expectation, slicing an extraordinary 0.26 seconds from his personal best in a race that instantly became one of the greatest ever run.

The achievement sent shockwaves throughout the track and field community. While Tharp arrived in Eugene as one of the leading contenders for the NCAA title, few envisioned a performance capable of redefining the limits of the event. Instead, the American hurdler delivered a race for the ages, combining flawless technique, explosive speed, and impeccable rhythm from the first hurdle to the finish line.

The historic run not only secured his place in athletics history but also transformed the outlook of the championship. With the world record now in his possession, Tharp advances to the final as the overwhelming favorite, carrying momentum that could make an already unforgettable weekend even more extraordinary.

For years, the 12.80 barrier appeared untouchable. On a stunning day at the NCAA Championships, Ja’Kobe Tharp proved otherwise, producing the kind of performance that reminds fans why sport remains so unpredictable. In a matter of seconds, he turned a routine qualifying round into a landmark moment that will be remembered for generations.

The world record no one saw coming is now a reality—and Ja’Kobe Tharp is the man who changed history.

A new chapter in middle-distance running may have begun in Oslo after American teenager Cooper Lutkenhaus produced one of the most remarkable performances of the season, narrowly defeating reigning Olympic champion Emmanuel Wanyonyi in a thrilling men's 800m contest at the Diamond League meeting.

The 17-year-old sensation shocked a world-class field by crossing the finish line first in a race that came down to the smallest of margins. After an intense battle over the final metres, Lutkenhaus held off Wanyonyi by just one hundredth of a second, producing a dramatic finish that left the packed stadium in disbelief.

From the opening lap, the pace was relentless as the leading contenders positioned themselves for a fierce showdown. As the athletes entered the home straight, Wanyonyi appeared poised to unleash his trademark finishing kick. However, Lutkenhaus refused to be intimidated, matching the Olympic champion stride for stride before producing a perfectly timed lean at the line to secure a historic victory.

The result marks a breakthrough moment for the young American, who continues to establish himself as one of the brightest talents in global athletics. Defeating an Olympic champion at a Diamond League event is a feat many athletes spend entire careers pursuing, yet Lutkenhaus achieved it before reaching adulthood.

For Wanyonyi, the narrow defeat does little to diminish his status as one of the world's premier 800m runners. The Kenyan once again demonstrated his exceptional class and competitiveness, pushing the race to a world-class standard and forcing his young rival to deliver the performance of a lifetime.

Beyond the result itself, the race offered a glimpse into what could become one of the sport's most exciting rivalries in the years ahead. With established stars and emerging talents now pushing each other to new heights, the men's 800m continues to evolve into one of athletics' most captivating events.

On a memorable night in Oslo, the spotlight belonged to Cooper Lutkenhaus. At just 17 years old, he stood toe-to-toe with an Olympic champion and emerged victorious, announcing himself to the athletics world in spectacular fashion.
