This post has been inspired by an article I just read in June's TraiRunner magazine.
It talks about Diana Finkel's '2nd place overall' finish, 'first woman finisher', and record setting time at the Hardrock 100 mile race in 2010. It also talks, in depth, about the kidney failure she suffered and how she could have died.
The article was very eye opening.
Please take some time to check out the magazine article and do some investigating on your own...... It's a serious matter and you should know the warning signs.
