We are thrilled to announce that Boulderthon™ remains scheduled for October 11th, 2020. We will continue to monitor & work closely with state & local officials on the latest covid-19 developments. We are in the process of assessing any and all modifications needed for runner and participant safety, including, but not limited to, staggered starts, course changes, & a new participant cap. In the event that we must postpone, all runners will have the option to defer their entry to either the next edition (Spring 2021), or the subsequent edition of the race (your choice), at no charge.
