During Eluid Kipchoge’s build-up to the Ineos 1:59 Challenge, where the Kenyan legend became the first human to break the sub-two-hour marathon, his training week contained a mix of hard and easy efforts, strength work, and track training.
Time and time again, in Africa and all around the globe, the best road runners include at least one track session a week. And yet, track running is something that’s rarely utilized by recreational runners.
The Science Behind Track Running
The evidence behind interval training for not only runners, but any endurance athlete, is conclusive. These bursts of high-intensity work followed by brief rest periods build the top-end speed missing from one-paced amateur athletes who spend too long training in their mid-zone.
There is some evidence that suggests that intervals on the track are more superior to similar intervals completed on trails, road or park. 42 recreational runners were recruited by U.S. scientists in 2018 and split into the following two groups:
Control group: This set of runners trained three times a week for 10 weeks at 75% of their VO2 max (a moderate intensity). Their runs started off at 30 minutes and built up to 40 minutes over the 10-week period.
Track-training group: This set of runners also gradually increased in volume like the control group, but all their runs were done on a 400 m track. Instead of running at a constant pace, they ran hard for 200 m and then walked or jogged the next 200 m.
Before and after the 10-week programme, every runner undertook a range of tests to lift the lid on their physiological make-up. These included maximum oxygen uptake (VO2 max), anaerobic treadmill run to exhaustion (achieved by running 12 km/hr at a 20% incline), isokinetic leg extension and leg-curl strength, and 50 m sprint times.
The researchers found that while both groups enjoyed similar increases in their aerobic capacity, the track-training group experienced numerous additional gains. Perhaps unsurprisingly, their anaerobic time to exhaustion, sprint times, VO2 max, and leg strength all improved. Interestingly, the track group also lost significant body fat, while the control group didn’t.
Clearly the speedwork was of benefit to the track-training group, but the precision and ease with which the athletes could complete each session helped, too. The track’s controlled environment is perfect for speedwork where maximum gains can be enjoyed by precise work-and-rest load — simply turn up with your watch and run.
Surface for Speed
Not all tracks are equal. The finest tracks are artificial, providing a smooth surface with good grip and nice cushioning that’s fine in all weather. Asphalt tracks, on the other hand, are incredibly durable, offering a strong grip but lacking in cushioning. Then you have old-fashioned cinder tracks — the like of which Roger Bannister broke the four-minute-mile on — that lacks cushioning but does offer a reasonably level surface.
While track surfaces might vary in quality, a weekly* session that’s precisely measured will not only improve your running performance but also add a sprinkling of variety and fun, too. But be forewarned by the emphasis on “weekly” sessions, especially if you’re a relative newcomer to speedwork. Intervals are demanding, leading to greater muscle damage than easy running, which can soon lead to injury if you don’t recover sufficiently.
If you’re new to track training, take it easy by doing just 3 x 400 m hard efforts initially (plus a warm-up and cool-down). From that point, you can build up your efforts over a period of months, by adding an extra 200 m or 400 m per week.
It’s also worth keeping your sessions relatively short — a targeted 35-minute session is much better than aimlessly running around in circles for 1.5 hours. Note that you should always avoid the track if you’ve had a recent injury.
