Trail Golf Endurance Challenge
Valparaiso, United States • 27 Jun 2026
Event
The Trail Golf Endurance Challenge is a trail running event held at Trailyard Outpost, 2651 Clifford Rd, Valparaiso, IN. Distances offered include:
- 50K
- 10M
- 50K Relay
- 10M Relay
Registration opens December 27, 2025. The 50K covers nine routes called "Holes" and the 10M covers three Holes.
Format and rules
Each Hole is a loop of about 3–4 miles with average gain near 190 ft per Hole. Total elevation gain is about 1700 ft for the 50K and about 500 ft for the 10M. Runners start each Hole together, complete the designated course, and then have time between Holes for rest and support from their crew, called "Caddies."
Scoring uses golf-style strokes instead of pure elapsed time; examples given are Eagle = 2, Birdie = 3, Par = 4. Time windows for each Hole determine the stroke received. Skipping or not finishing a Hole results in a Triple Bogey (stroke score of 7). Veering off course may incur at least a 2-stroke penalty. In a score tie, the lower cumulative time on course is the tiebreaker.
Aid and logistics: there will be water, Tailwind, and coffee available for runners only; no on-course aid or water stops are provided and runners must carry needed hydration and fuel. Relay teams must be 2 or 3 runners, with only one teammate on course at a time. Visit the organization's website for the most recent information.
