I'm taking part in my first Olympic Distance tri this Sunday. So far, I've several sprints, as well as biathlons, but this weekend will be my first 'real thing'.

I'm feeling a bit apprehensive - wondering if I've trained enough, if I'll make it without collapsing (!) etc. Any tips for prep?

Also, any tips on nutrition? I foresee that I'll take abt 3 hours to complete it, any advice on pre (race starts at 8 am) and during race nutrtion? I get stitches REALLY easily, so am a little scared to drink to much on the bike.

Thanks!
