2010 Calvin’s Challenge
The 19th Annual Calvin's Challenge
Saturday, May 1st, 2010.
Registration is now open.
Early registration discount deadline is January 15, 2010
Calvin's Challenge 12 Hour Bike Race is held each year on the weekend before Mother's Day, starting at Shawnee High School in Springfield, Ohio.
Male and female age classes start at age 10 and increase in 5 year increments. Classes including traditional bikes as well as:
• 3 Tandem classes
• Triples
• Recumbents
• HPV
• High wheelers
• Singlespeed/fixed gear
We hope this will give more people a chance to compete with riders of similar abilities. There are custom designed medals for 1st three places in each class. Printed results and medals will be handed out 30 minutes after the finish.
We believe this is the best organized 12 hour event in the U.S. as well as the best marked route of any ride. Both the 50 mile long loop and the 7 mile short loop are flat to rolling on lightly traveled roads. Drafting and aerobars are allowed.
Since we encourage new riders to test themselves, we offer a non-racer option on the same route that includes a map and snacks.
Bike mounted or helmet mounted mirrors are required for all riders.
Back for 2010!2 & 4 Person Relay Teams
We tested relay racing in 2009, and are pleased to offer it again in 2010! Relay team racing could be a means to do a final team shakedown prior to racing RAAM, or a means to have an intense competitive experience with your racing team, or a way to introduce your weekend warrior friends to an ultra event in a non-threatening way. As tested last year, we’ll allow racer exchanges at designated checkpoints only. This would demand 25 mile shifts for at least the first 100 miles, and 7 mile shifts thereafter.
