Too late?
 

Is it too late to join this Challenge? I just joined this site and I need a challenge!

There isn't a Biggest Loser Challenge currently running. There's an sub-forum called Chicks Up For A Challenge, there's always something going on there!

When's the next one starting?

There's a new one starting this month on 4/22 called "Spring into Summer." Make sure you sign up over on the Biggest Loser thread and add your starting weight. Good luck!
