Important Update

Why 15K Instead of a Half Marathon? We originally planned to include another area of the ranch to bring the course up to half marathon distance. That section isn’t going to work as we’d hoped this year, so the inaugural Lone Tree Reckoning will use the loop we have: just over 15K.

• Understanding Changes: Some runners were looking forward to a half marathon, and we apologize for the change.
• Course Features: This loop still incorporates the climbs, technical terrain, and variety we aimed for.
• Excitement: We’re excited for you to experience this first Lone Tree Reckoning.
• Get Ready: The trail is waiting. Are you ready for the Reckoning?
