Welcome to registration for the 2026 RIM ROCK MARATHON & HALF.
This event is being produced with people who run, work, and play in the Grand Junction community, and we couldn't be prouder to have you join us.
Register by 10/1 to have your name printed on the front of your bib. After 10/1, they will be written on the back.
Visit grandjunctionsports.org/rimrockmarathon for event details, including course maps and more.
Please contact the Grand Junction Sports Commission with any questions or support needed during the registration process. We are always looking for volunteers as well; direct any interested individuals our way.
In the unlikely case of severe weather, or any other external issues that prevent the event from taking place, all athletes will receive a FULL REFUND or have the option to defer their entry until 2027. No refunds otherwise. Deferrals will only be accepted until Monday, 10/26.
