Register for Calvin's Challenge 2014

May 3, 2014

Bike RegOnline registration will continue to be through Bike Reg. We have made some changes for the 2014 year.

  • ONLINE REGISTRATION ONLY
  • NO MAIL IN AVAILABLE
  • NO DAY OF REGISTRATION

We have taken a lot of time to build out this years registration. We now have 3 events to register for

A nice feature of this work is you will be able to see who is your competition in your exact race category. Click on the above race you would like to register for and go straight to the registration page.

Remember that we offer an early registration discount that helps you keep the cost as low as possible and it helps us plan for the expected number of participants. We have two dates, the first early registration discount ends February 15th ($10 increase), the second one ends March 30th ($15 increase). After last year's record number of participants we have given thought about the need to institute a field limit for the number of racers we put on the local roads, particularly the 7 mile short loop later in the afternoon, so register early. We are concerned about your safety and the safety of the other road users. We want to remain a welcomed guest in the community.

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, depending on the class. 

Classes including traditional bikes as well as:
• 3 Tandem classes
• Singlespeed/fixed gear
• Recumbents
• HPV
• High wheelers
• Triples
• Trikes
• 2-person team
• 4-person team
• Ellipticals (check out their Facebook Page)

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 2013!

2 & 4 Person Relay Teams (12 hour race only)

Relay style racing has become quite popular in ultra endurance events. The Race Across America is exploding with relay teams, which is reducing the barriers to entry for many potential competitors.

Relay team racing could be a means to do a final team shakedown prior to racing RAAM,  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.

We allow racer exchanges at designated checkpoints only. 
This requires 25 mile shifts for at least the first 100 miles, and 7 mile shifts thereafter.
