Last year my friend, Stacey and I took a Yoga for Runners course at Downward Dog Yoga Studio. The course was excellent - especially for lengthening the hamstrings which get tight when running.

I found this site which illustrates some great yoga stretches for runners, which you might wish to try out:

Happy running

An interesting, albeit, odd fact from the people at Nike.

Apparently each foot sweats 2 cups of water during a marathon.

Have yet to run a full marathon so I am not sure if it is true. Odd though.
