Is Sven making a mistake?
If I really wanted to know, I’d check:
Runner’s world forums are really among the best on the internet, for some reason. I’m no big runner but it’s a friendly crowd when I’ve gone and easy to get registered on.
But I do run plenty, some cold water feels like it could do a good trick on the burn in legs.
Sister magazine of Runner’s World Forums are here too, http://www.runnersworld.co.uk/defaultForum.asp?sp=&v=6
