i have just had the afternoon off college as my 'Games' sport is biking.

the weather was crappy so i came home 

however it was decent weather at home so went DH'ing. well i have some small private DH trails by my house and have been riding them all afternoon.

now these are small, like 15-20 seconds each (however very fast and pedally)

i was riding these and pushing up for about 2 hours and started to get knackard. then i found myself unvolentarily (sp) throwing up after a run.

is this just my bodies way of saying, 'jeez man, take a break and eat something'?

or is there something wrong with me?

does this happen to anyone else after long, hard bursts of riding?

Some people throw up after doing intense physical activity like long distance running etc.... It could be this, but seeing as your only doing 20 second runs at a time it sounds doubtful.

Do you feel knackered after a run?

no, not knackard after each run, but i am lik erunning back to the top and doing continuous runs  


wasn't so hot, but i suppose i wasn't drinking that much just coming in for a quick swing of water.

could lack of water intake be the cause then?

normally i'm very sensible and when out on big DH rides will back a 3l water bladder.

Haha, are you going round every post in  Health/The Plaster Cast and making it sound dodgy!?

See your doctor, he'll check you out.
I'm being sick twice a day when i eat or exercise, and its due to an infection i didn't know about...
