We've got one last 2013 challenge for you to take on over the Christmas period; the Mile Muncher 150.
The challenge starts December 14 and you've got shorter than usual to complete this one, with the challenge ending on January 5.
You can take on 50 miles a week if you like, two rides of 75, or even the whole 150 if you're really feeling good - it's completely your choice.
If you finish the challenge, you'll be entered into a prize draw for a chance to win a cycling goodie bag worth £100.
