The next 4 week challenge starts Monday, January 1st, and runs to Sunday, February 4th.
This challenge is a special 4-5 week beginning of the year challenge.
For those of you who are ready to start now, the challenge will start January 1st and will run through February 4th, for a total of 5 weeks.
However, we totally understand that many people are either traveling, crazy busy with the holidays, or just finding Nerd Fitness for the first time the first week of January - but we still want you to join in on the fun! If you're in this group, your challenge starts anytime in the first week of January, and still runs to February 4th. Your challenge will be the standard 4 weeks.
After this challenge ends, on February 4th, we will go back to our normal schedule in which each challenge lasts 4 weeks with 1 week off in between.
