Complete a 1km and a 5km time trial to determine your running power threshold (Critical power rCP) and running power training zones.

Distances don't need to be exactly 1km and 5km. They can be 1 mile and 3miles or 1km and 10km. The aim is to select a distance that will be 1. less than 5min, 2. greater than 10min.
