How to avoid peaking?

There's no such thing as peaking.

More miles?

Increased mileage may force you to slow down the workouts and when you need to start feeling fresh begin your taper and peak.

I peaked your mom.

Peaking comes from being well rested, it doesn't have anything to do with the speeds you're hitting in training.

However, because faster running puts greater stress on the body, many people scale back their mileage when running very fast workouts in order to stay healthy. That could be why you associate fast running with peaking.

Generally, these are the dangers with doing fast workouts too soon:

1) You're forced to reduce the overall workload volume in order to remain injury free. This could result in a loss of fitness after a while.

2) Perhaps you haven't maximized the physiological benefits that come at slower speeds yet. Milers need to spend several months each year working on their VO2 max before moving on the fast stuff like 400's. That's why they run cross country in the fall. If you start doing 400's in October, you're going to neglect an important system.

3) You need to be able to "progress" in your training. If you hit very fast workouts very soon in the year, what do you do next? If you can't go any faster, you're just going to stagnate.

With all that said, very fast running has a place in your program year-round.

You never want to ignore any system. You may not focus on the really fast stuff in the fall and winter, but you need it there in small doses.
