Mapmyrun

Does anyone use mapmyrun? It is a very cool site where you can measure, save and store running routes, dead simple.
Anyway, I have created a North Herts Road Runners group so we can share routes with each other, the URL is http://www.mapmyrun.com/community/groups/742848129 and if you have an account already you can join the group...so come and join me!
