When it comes to technique, we are all about holding TUF. We give our athletes a technique they can replicate even when in a highly fatigued state. Speed, as well as endurance, comes from holding a manageable technique under pressure of effort. If an athlete can't handle the technique and be able to replicate it over the duration of their race distance, then it's not manageable. When technique is not manageable, the performance breaks down with the degrading of the technique as they fatigue. Many a world champion has had questionable techniques in regards mechanics but have been able to control their particular technique for long periods under fatigue - as well as the pressure of competition.
