Calvins Challenge - Springfield, OH - 50.8 mile course recon

This is a course recon for the 50.8-mile Calvins Challenge loop. It is used for the 100-mile, 6-hr, 12-hr, and 24-hr races. There is also a smaller 6.9-mile loop that features similar roads and terrain. I went to Springfield the weekend before I rode in the 12-hour drafting race and recorded this course recon. It is presented here in its entirety to give people an idea of what to expect in the race. (note the route is subject to change in the future) I also made a video of my race - check it out here:    • My First Race Win! - The 2025 Calvins Chal...   Here are links to the loops on RideWithGPS: 50.8 mile: https://ridewithgps.com/routes/7576957 6.9 mile: https://ridewithgps.com/routes/7576965 If you enjoy my videos, consider buying me a coffee! https://buymeacoffee.com/ericbarnett (thank you!) ------------------------------------------------------------------------------------- Follow me on Instagram: @ericbarnettcycling Like, share, and subscribe for a lot more content! ------------------------------------------------------------------------------------- #springfieldohio #calvinschallenge #endurancecycling #roadcycling
