Challenges???

Macknbee

I'm new to this site and I noticed that there were lots of "challenges" posted on the forum, but most of them are closed. Where is the best place to look for new ones? I really want to get involved in a team challenge but I am definately not in the shape to run miles yet, so if anyone has any challenges or suggestions I may be able to join, please let me know!!!

Cheers,
Heather
