Predict how “pro” you will be, in comparison to the big dogs. For this side challenge, we will only keep track of mileage. However, we encourage you to compare your stats to the professional of your choice.

The Tour de France Challenge started in the late 1990’s, in Casa Grande, AZ. Mark was an employee of Round Trip Bike Shop, working for owner, Kent Taylor. Kent enjoyed following Le Tour de France and saw an opportunity to encourage his friends and customers to ride more. He challenged everyone to ride for 45+ minutes (consecutive) each day the pros ride during the Tour. This meant that participants would have to ride 21 of 23 days. As a young man, Mark enjoyed participating in “the challenge” and enjoyed watching the competition ensue, year-after-year, between Kent and the other super studs of the area. Mark purchased Sun & Spokes Bicycle Shop in June of 2012 and has challenged others to the Tour de France Challenge each year. There have been various side-challenges that have emerged over the years. The 2017 TDFC included five optional Epic Experience Rides. The 2018 edition of the Tour de France Challenge gives you the opportunity to see How "Pro" can you go!
