A few weeks ago after a long, hard run I peed.It was very red, thick and obviously blood. No other problems, no other discomfort etc. I drank lots of water as I knew I was dehydrated, had foolishly gone out without any drink. The weather was hot and clammy. After downing a litre of water I peed clear again. After a weekend of frantic google searching and convincing myself I had cancer I went to GP. Ran a urine test which came back clear' He said it wasn't uncommon for runners to have blood in urine after a hard run-first I'd heard of it. He said not to worry about it.
Today it's happened again, any thoughts?
Thanks
