To participate in the winter challenge, you do not have to ride every day between Dec. 15 and March 15. Ride as often as you can. Enter your ride data from each ride separately in the activity tracker of your profile on the website. 

Each day you enter data counts as one ride. Do not total up multiple rides and enter the data that way. You will cheat yourself out of days ridden!

You must ride for a minimum of 30 minutes for each day of riding.
