Virtual Cycling Challenge

The annual KIWL 500:5000 Challenge takes place from October 1st-31st each year, with participants challenged to ride at least 500kms and/or climb 5,000 meters of elevation during the month, using the Strava App as their activity tracker. Ride anywhere, any time, on your own or in a group, at your own pace, any ability is welcome.

You will be entered into a fantastic prize draw if you achieve either discipline. You will be entered twice if you achieve both! You could win hotel experiences courtesy of the IHG Hotels, and other great prizes, including Castelli online store vouchers!
