Jackalope Jam

The Jackalope Jam is a multi day timed event held in Cat Spring, Texas from February 18 to February 22, 2026. It offers solo and ruck divisions and a separate team relay. The venue is 7IL Ranch at 5387 Mill Creek Road with course side camping and open access during the event week.

The format uses an out and back loop exactly 2 miles in length, one mile out and one mile back, on a short grass and gravel farm road. Only fully complete laps count toward a participant's distance. There is one main aid station at the start and finish that is stocked with substantial food and supplies for overnight participants. Runners may set up their own tents and support areas along the course. It is common for participants to take long rest breaks, sleep, or leave and return later to add more miles.

All participants receive a medal. Solo competitors who complete 100 kilometers or more receive a buckle. Ruck participants can earn bonus patches.

Distances and formats include:

  • 6 hour solo and ruck
  • 12 hour solo and ruck
  • 24 hour solo and ruck
  • 24 hour relay teams of 2 to 6 people
  • 48 hour solo and ruck
  • 72 hour solo and ruck
  • 100 hour solo and ruck

Relay teams compete in all male, all female, or coed divisions and exchange only in the start finish exchange area. Refund and team registration rules apply during the registration period. Visit the organization's website for the most recent information.
