I am a new runner - up to 8 miles on my long run. After the long run I have blood in my urine. My doctor has suggested it may be connected with my trainers ! A condition called March something something (so called because soldiers suffer from it due to trauma of marching.) If it is not this we will have to look at renal function. Has anyone heard of this 'marching'condition? or had similar physical response to running.

Doubt whether it's too serious from what I remember of the most likely cause.
Didn't Frank Shorter (Olympic Marathon champion 1972) regularly suffer from this problem?
Apparently its something to do with the repetetive jolting that running does to your insides. Most of the time, the body can take it but when you push it too far, there is some 'leakage'.
There was an article on it on the RW website - where it is, I don't remember.

Had the same thing a couple of times after long runs in the past. No pain or discomfort, just very freaky (looked like strong tea with reddish tinge) and had totally cleared up by the next time I went to the loo after rehydrating.
I've read one explanation of it being due to the bladder being empty for a long time in the first few miles of the run leading to internal friction and some bleeding. This would make sense as I'm an early morning runner and probably wasn't hydrated enough before the run.
if you ae well and no other symptons just observe, should settle. Make sure you are well hydrated but if no better see your GP with a urine sample for testing and a review
Excellent link. Looks like I might have experienced myoglobinuria. Glad I didn't read that at the time as it would have scared the hell out of me. Still....like I said, it had totally cleared up the next time I went.
