Firewater Ultra : event overview

Firewater Ultra is a trail running event held on the East Lakeshore Trail along the east side of Tellico Reservoir in Greenback, TN. This is the 11th edition. Distances offered include:

  • 100K
  • 50K - 2 Per Relay
  • 50K Sunrise
  • 50K Sunset
  • 25K Ruck (about 22.5K)

The finish line is at the southern terminus of the trail, Wildcat Pointe (Trailhead #10). Organizers provide published documents with details on aid station locations, distances between aid stations, cutoff times, crew access, drop bag locations, and pacer rules.

Course format and 25K Ruck details

The 100K course runs the full length of the trail out to Canal Branch Trailhead (Trailhead #1) and returns to Wildcat Pointe. The 50K course begins at the northern end at Canal Branch and runs back to Wildcat Pointe. Both 50K options travel the same north-to-south section; the Sunset option starts later in the day and runners should bring headlamps. The 50K Relay splits the 50K course between two teammates; the first leg meets the second at Sinking Creek Trailhead (Trailhead #4) so the second leg can finish at Wildcat Pointe.

The new 25K Ruck covers roughly the second half of the 50K course. Ruck weights are specified as dry weight: male/non-binary 30 lb, female 15 lb, boys under 15 - 20 lb, girls under 15 - 10 lb. Weigh-in is required 30 minutes to 1 hour before the event begins, and removal or reduction of weight during the event is not allowed. Finisher recognition for the Ruck includes a custom patch at weigh-in. Visit the organization's website for the most recent information.
