Michelob London Triathlon

I did my first drafting Olympic distance race on Sunday, it was such a fantastic experience to race in a senior elite field.
The swim was fast, very fast. There were 3 leaders that i managed to hang on to for about 700m then i got dropped, i was suffering so bad after that buti kept pushing as i knew i had a good minute lead over the next pack of swimmers. I had a clean transition becasue there was noone around and just as i was mounting my bike i heard the commentator shout "here comes Dillon, Whitcombe and Cave" I couldn't beieve i had beaten them out the water by so far!!
I decided that it wasn't worth me chasing down the 2 girls thats were leading as they were to far away so i sat up and waited for the chase pack to come through.
It was awesome to be in a bike pack with athletes who i admire, who i used to watch on TV several years ago and wish i could one day be like them.
As soon as i got on the run i knew there was something wrong.... i had nothing... i didn't know if it was the heat or nutrition so i tried to drink as much as i could and took a gel. It didn't help, i trotted along at an agonsing pace, 4mins off my usual pace. I kept pushing as i knew i was in 7th place.
I don't remeber much after i crossed the line, i collapsed and was taken to the hospital tent on a stretcher. When i came round i was coverd in ice, had an IV and oxygen. My temp was 41.8!!!
After a few hours and a few bags of fluid i was good enough to leave and my temp was back down.
Im ok today, took a day off to get over the heat exhaustion. I went for a 60min run yesterday, nice and easy.
