Maximize Mixed Intervals

Schedule mixed intervals for the peak phase of training to help sustain fitness adaptations earned earlier in the training cycle.

Triathletes who phase out very high-intensity training altogether in the peak phase tend to lose their highest gears and become two-speed athletes who quickly fall apart whenever they exceed their average goal race pace.

I recommend a descending format for mixed-interval workouts, with the slowest intervals first and the fastest intervals last.
