I break my lactate threshold and marathon pace workouts into intervals.

Training in intervals provides a similar benefit but is less stressful than longer blocks of time.

By breaking the work into intervals we can extend workouts, go longer, and do more volume.

A short recovery period helps us recover and lets us do more work.

We don’t fatigue as fast with a brief recovery period.

Rather than dying off at the end of a workout and struggling to hit paces we can finish strong and do better quality work.

Intervals are an efficient and effective way to train.

For example:

Instead of a 30 minute lactate threshold workout, I could break it into 6 x 5 minutes, 3 x 10 minutes, or 2 x 15 minutes.

Instead of a 60 minute marathon pace workout, I could break it into smaller chunks.
