[QUOTE=jock]Lactic acid doesn't build up in the stomach, CUT QUOTE]

thanks thylo and Jock. shows that my understanding of physiology was not up to scratch, i was under the impression that lactic acid ended up in the stomach and when it got built up thats what makes you want to blow chunks.

i figured that once it has happenda couple of times it will get better. my pre race eating plan was in disaray with the staggered start. also suffered from having dirt crit fitness , where i was fine for the 1st 20 or so minutes (dirt crit length) then POP, the pressure valve went...... will work on it some more with the race up at ourimbah this weekend.

comforting thing was that my 1st lap was a 28 minute lap, where the middle c graders were doing that. if i hadnt blown up i may have matched their times.
