Interval Training for Busy Amateurs
Intervals are the highest-return session an amateur can run, and the easiest to get wrong. Done once a week with full recovery between efforts, they raise VO2max and race pace sharply. Done three times a week on tired legs, they produce stagnation and injury. One quality session beats three sloppy ones.
Three workouts that cover the bases
Rotate three simple formats across a training month. Short repetitions of 200–400 metres sharpen speed, classic kilometre repeats build threshold, and longer cruise intervals of 1200–2000 metres teach race rhythm. Each session needs a fifteen-minute warm-up with drills and strides before the first effort.
Session menu
| Workout | Structure | Recovery |
|---|---|---|
| Speed sharpening | 8–10 × 400 m | 200 m walk/jog |
| Threshold | 4–5 × 1000 m | 90 s jog |
| Cruise intervals | 3 × 2000 m | 2 min jog |
Pacing and effort
- Start conservative: the first two reps should feel almost too easy; the last two should require focus.
- Even splits win: if rep five is ten seconds slower than rep one, the session was too fast.
- Stop early, not late: end the workout when form slips, not when the plan says so.
Fitting it into the week
Place the interval day after a rest or very easy day, and follow it with your easiest session of the week. A Tuesday evening track session with Wednesday off works for most nine-to-five schedules. If work stress spikes, swap the session for an easy run — intervals on a fried nervous system teach nothing.
Log every session with times and a one-line note on how it felt. After six weeks the pattern in that log tells you more than any fitness score on a watch.
