Spending time running at or near your threshold pace will develop your ability to sustain a fast past and also build your tolerance to lactic acid. This session is great for all runners and triathletes. 10km runners will benefit from this session style as it simulates race effort. Longer distance runners even including ultra-runners will also benefit as your effort will build to this intensity on long sustained climbs.
