Exciting improvements; same great N24HC!

We’ve made a few changes – including non-stop checkpoints and a single daytime loop with closer checkpoints and better facilities! And a better Sunday breakfast!

The 2020 National 24 Hour Challenge has been selected as the World Ultra Cycling Association’s 2020 North American 24-Hour Championship event for both the Women’s and Men’s divisions! We are honored to once again be unanimously selected by the board of the WUCA as their North American 24-Hour Championship event, having served as the championship event most recently in 2017.

If you would like to be eligible for the 2020 North American 24-Hour Championship, you must be a member of the WUCA. To become a WUCA member, go here. (And then come back here!)
