As a youth (15-18), I swam only 100 meter breaststroke (short course) and 50s only in the medley. I've been swimming masters now for nine years (now 63) and I've only done 50s and a few 25s. I am entered in a 100 meter long course event tomorrow (and also swimming the 50).
Just want to know what I should do today, pre-race tomorrow, and between events (100 is first) in terms of eating, supplements, stretching, sleep, warm-up tomorrow, etc. I have P2Life Enduroboost and the Nutriboost powder. Let's suppose I did everything exactly right, how much of a difference could all this make in my performance?
Additional Questions: My LCM best is 39.8, but I feel pretty gassed at the end of a hard 50, so I'm guessing my aerobic fitness is not where it could be. What's a reasonable time to expect? I seeded myself at 1:40, but hope to do much better than that. And then what about race strategy? So while I understand 100 m is supposed to be a sprint, should I conserve some on the first lap or just go all out and see what happens?
