Maximizing speed and performance in distance running can be achieved by improving lactate threshold and running economy. While VO2max—the maximum volume of oxygen your muscles can consume per minute—has received most of the attention among runners and coaches, a high VO2max alone is not enough to attain competitive performances.

A high VO2max simply gains one access into the club, since a runner cannot attain a high level of performance without a high VO2max. But, while you can improve your VO2max, it is largely genetically determined.

The other two major physiological players of distance running performance—lactate threshold (LT) and running economy (RE)—influence your performance more, and are more responsive to training.

From the time of the classic study published in Medicine and Science in Sports and Exercise in 1979 by some of the most prominent names in exercise physiology—Farrell, Wilmore, Coyle, Billing and Costill—research has shown that the LT is the best physiological predictor of distance running performance.

LT is an important physiological variable that demarcates the transition between running that is almost purely aerobic and running that includes significant oxygen-independent (anaerobic) metabolism. It represents the fastest speed you can sustain aerobically. Since the LT represents your fastest sustainable pace, the longer the race, the more important your LT.

What is LT Pace?

LT pace is about 10 to 15 seconds per mile slower than 5K race pace, or about 10K race pace for runners who take 40 minutes or more to complete 10K. If using a heart-rate monitor, the pace should be about 75 to 80 percent of your maximum heart rate. 

For highly trained and elite runners, LT pace is about 25 to 30 seconds per mile slower than 5K race pace, or about 15 to 20 seconds per mile slower than 10K race pace, and corresponds to about 85 to 90 percent max heart rate. The pace should feel "comfortably hard."

How to Improve LT?

Sample workouts to improve lactate threshold include:

Continuous runs at LT pace, starting at 3 miles and increasing up to 7 to 8 miles, or about 45 minutes for marathoners

Intervals at LT pace with short rest periods, such as 4 to 6 x 1 mile at LT pace with 1 minute rest

Shorter intervals at slightly faster than LT pace with very short rest periods, such as 2 sets of 4 x 1,000 meters at 5 to 10 seconds per mile faster than LT pace with 45 seconds rest and 2 minutes rest between sets

Long, slow distance runs with segments run at LT pace (for marathoners), such as 12 to 16 miles with the last 2 to 4 miles at LT pace, or 2 miles + 3 miles at LT pace + 6 miles + 3 miles at LT pace.

How Running Economy Makes Running Easier

Running Economy is the volume of oxygen consumed at submaximal speeds. In 1930, David Dill and his colleagues were among the first physiologists to suggest that there are marked differences in the amount of oxygen different athletes use when running at the same speeds, and that these differences in "economy" of oxygen use are a major factor in explaining differences in running performance in athletes with similar VO2max values.

For example, research has shown that, while Kenyan runners have similar VO2max and LT values as their American or European counterparts, the Kenyans are more economical—possibly due to their light, non-muscular legs that resemble those of thoroughbred race horses. The heavier your legs, the more oxygen it costs to move them.

RE is probably even more important than the LT in determining distance running performance because it indicates how hard you're working in relation to your maximum ability to use oxygen. 

For example, if two runners, Jack and Martin, have a VO2max of 70 milliliters of oxygen per kilogram of body weight per minute and a LT pace of 7 minutes per mile, but Jack uses 50 and Martin uses 60 milliliters of oxygen while running at 7:30 pace, the pace feels easier for Jack because he is more economical. Therefore, Jack can run faster before using the same amount of oxygen and feeling the same amount of fatigue as Martin.

I have yet to see a runner who has superior RE who does not also have a high VO2max and LT.

4 Strategies to Improve Running Economy

Despite its importance, RE seems to be the most difficult of the three physiological players to train. While many runners and coaches think that RE is a reflection of running form, it is more influenced by those microscopic structures that influence oxygen delivery to and use by the muscles—capillaries and mitochondria, the densities of which are both enhanced with high mileage.

Research has shown that runners who run high mileage—more than 70 miles per week—tend to be more economical.

In addition to increasing mitochondrial and capillary density, the greater repetition of running movements may result in better biomechanics and muscle fiber recruitment patterns and a synchronization of breathing and stride rate, which may reduce the oxygen cost of breathing.

RE may also be improved by the weight loss that often accompanies high mileage; the change in body weight lowers oxygen cost.

Since VO2max plateaus with about 70 to 75 miles per week, improved RE may be the most significant attribute gained from running high mileage. However, it's not entirely clear whether high mileage runners become more economical by running more miles or they're innately more economical and can therefore handle higher mileage.

Intervals and tempo runs can also improve RE since, as VO2max and LT improve, the oxygen cost of any submaximal speed is also likely to improve.

However, it is possible to become more economical without improving VO2max or LT, as research on power training with very heavy weights and plyometrics has shown.

Power training focuses on the neural, rather than metabolic, component of muscle force development to improve RE.

The future of American distance running may have just announced itself.

Luke Surface, an 8th-grade student-athlete from North Raleigh Christian Academy in Raleigh, North Carolina, delivered a performance that stunned the track and field community after taking on some of the nation’s best high school runners at Nike Outdoor Nationals.

Competing at the legendary Hayward Field in Eugene, Oregon — one of the most iconic venues in American distance running — Surface lined up in the boys championship 5,000 meters against a field dominated by high school seniors, including several athletes preparing to compete at the NCAA Division I level.

Despite being one of the youngest runners in the race, the 14-year-old held his own against the elite competition, finishing eighth in an incredible 14:25.88. The performance set a new national middle school record, averaging approximately 4:39 per mile for more than three miles.

That kind of time is fast enough to win many high school state championships across the United States and meets qualifying standards for several major NCAA Division I conference competitions — a remarkable achievement for a runner who has not yet entered high school.

But Surface’s historic 5,000m performance was only the latest chapter in a season filled with record-breaking moments.

Earlier in May, he clocked 8:52.03 for 3,200 meters at the NCISAA Division I State Championships in North Carolina, breaking another national middle school record. His converted two-mile time of 8:55.12 surpassed the previous world-best mark for a 14-year-old age group, previously held by Vincent Recupero.

During the previous cross-country season, Surface also made headlines when he ran 15:12 at the adidas XC Challenge, finishing second while competing against runners who were several years older.

Across cross country, two miles, and the 5,000 meters, Surface has continued to prove that his talent is far beyond his age group. While he still has four years of high school competition ahead before reaching the college level, his performances have already placed him among the most exciting young distance runners to watch.

The American high school 5,000-meter record currently stands at 13:32, set by Lex Young in 2023 — a mark Surface is not yet close to challenging. However, his remarkable progression at such a young age has caught the attention of the running world, with many eager to follow how far his extraordinary journey can go.

For now, Luke Surface remains an eighth grader rewriting the record books — and his story is only beginning.

DOHA, Qatar – Ethiopian distance running is once again making a powerful statement on the global stage. Following the Doha Diamond League meeting, Ethiopia has achieved a remarkable clean sweep of the women's 3000m/5000m standings, occupying all eight leading positions in one of the most competitive disciplines in world athletics.

Leading the charge is Likina Amebaw, who sits comfortably at the top of the rankings with 22 points. Close behind is fellow Ethiopian star Freweyni Hailu on 14 points, while Medina Eisa occupies third place with 12 points. The dominance continues through the rest of the leaderboard, with Senayet Getachew, Hawi Abera, Aleshign Baweke, Marta Alemayo, and Bernesh Dessie completing an extraordinary Ethiopian monopoly of the standings.

The achievement highlights Ethiopia's exceptional depth in women's distance running, where a new generation of athletes continues to emerge and challenge for global honours. Rather than relying on a single standout performer, Ethiopia has assembled a formidable squad capable of controlling races and collecting points across multiple Diamond League meetings.

While the current standings paint a picture of complete Ethiopian supremacy, the battle for the Diamond League title is far from over. Several meetings remain on the road to the season finale, leaving plenty of opportunities for rivals to close the gap and for positions within the Ethiopian contingent to shift dramatically.

For now, however, the spotlight belongs firmly to Ethiopia. The East African powerhouse has transformed the women's 3000m/5000m standings into an all-Ethiopian affair, sending a clear message to the rest of the world that the race for Diamond League glory will likely run through Addis Ababa.

The question now is whether Likina Amebaw can maintain her advantage and finish the season as the overall leader, whether Freweyni Hailu or Medina Eisa can mount a successful challenge, or whether another athlete will produce a late-season surge to rewrite the script.

One thing is certain: the road to the Diamond League Final promises a fascinating battle among some of the finest distance runners on the planet.
