How many Kilo(meters)s can you gain between Christmas eve and New Year's eve?
We'll be keeping track of how well everyone is doing by using a Strava challenge.
This will allow you to see how everybody else is doing too.
Any activity you do on Strava will count, be it skiing, indoor cycling or outdoor swimming!
It's not all about who collects the most kilometres though, we will have plenty of spot prizes on offer too!
Entry to this challenge will cost you a minimum CHF 50 donation to World Bicycle Relief, but as well as the joy of giving, this will buy you the chance to win any of these prizes:
