From stv on Tri-DRS:
Also, this: At some point in the race, things will get hard. That's not a bad thing; in fact, deep down, most people are looking for that point. Approach it slowly & back off, or push right through it ... but just remember, it's supposed to be hard, so accept it when it comes and then deal with it how you choose ... ease back, ignore, accept & push more. It's your choice.That's a part I haven't figured out for myself at all yet.
