This is an annual event, and it is going to be back in just over a week! Join Patrick Dempsey to help raise money for cancer. When Zwifters have ridden 50,000 miles across all events over the weekend, Zwift will make a $50,000 donation to the Dempsey Challenge. If you can’t make it to the rides on the 23rd and 24th, you can make a donation on their website. To sign up for the events, head over here: https://www.zwift.com/uk/dempseychallenge.
