The Miner 49er endurance runs take place on Saturday, November 8, 2025, in Dubuque, Iowa at the Mines of Spain area (8991 Bellevue Heights Rd). Distances offered:

  • 25K
  • 50K

Registration closes on October 31, 2025. Race registration fees are non-refundable and registrations are not transferable.

Course and logistics

The course is primarily single track with some double track and prairie trail. Runners will pass the Julien Dubuque Monument, Horseshoe Bluff, and views of the Mississippi River. The 25K is an out-and-back with about 2200 feet of elevation gain; the 50K covers the same loop twice, with about 4400 feet of gain. The route includes stone steps, stream crossings, rocks, and roots. Three aid stations will be on course and will be stocked with standard ultra-event nutrition. The event is held in a public park, so non-race trail users may be present.

Distance changes must be confirmed with the race director before the start of the race; switching from 50K to 25K carries no refund. Pacers are not allowed for either event. Packet pick up is at the EB Lyons Interpretive Center at 8991 Bellevue Heights Rd on the day before and the morning of the event. Visit the organization's website for the most recent information.
