Zumbro Endurance Run

2026 Zumbro Endurance Run Pre-Season Updates Thank you for your interest in the Zumbro Endurance Run 100 Mile, 50 Mile, 34 Mile and 17 Mile races. We are currently in the permitting process for the 2026 event. The tentative date(s) for the 2026 race(s) are Friday April 10 (100 Mile) and Saturday April 11 (50 Mile, 34 Mile and 17 Mile). Zumbro is an early season event and a snow cancellation is not out of the question. We are required by the DNR to hold the races prior to the commencement of turkey hunting which always begins the Wednesday closest to the 15th of the month. Please be sure to familiarize yourself with our no refund policy prior to registering. Registration is tentatively set to open on Thursday January 1, 2026. The information currently available on the website is for the 2025 race - the majority of the information for the 2025 race will be applicable for the 2026 race, but there may be some changes. Most of the significant updates to the event website will be made prior to registration opening. If you are interested in running the 2026 race we encourage you to review the information that is available now, but require that all of the information be reviewed again once it has been updated for the 2026 race, and prior to you registering for the race. We reserve the right to make changes to dates, the course, logistics, cutoffs, entry fees, the registration process, and any other aspect of the event - that said we do expect that most of the details will be the same as the 2025 race. Final details will be published late fall / early winter 2025 - please check back. You can join our mailing list HERE. You can join the Rocksteady Running Community HERE.
