Norris Ultra Dam Hard Trail Race : November 1, 2025, Norris Dam State Park

The event offers two trail distances:

  • 25k (one counterclockwise loop)
  • 50k (two loops of the same course)

Both distances run on single-track trails and jeep roads across Norris Dam State Park and the Norris Municipal Watershed. The 25k has a 4:40 finish limit; the 50k has a 9-hour finish limit. Runners attempting the 50k must reach the halfway aid station and depart that aid station within 4 hours to continue.

Course, logistics and rules

Multiple aid stations will be placed on the course and are accessible by road. Live GPS tracking is available at no extra cost through the Webscorer app; the app can send location updates about every five minutes to show positions on the course map. Results will be posted on RunSignup and Webscorer.

Accommodations at Norris Dam State Park include two campgrounds with water and electric hook-up and dump stations, plus rustic and deluxe cabins. Additional lodging is available near Exit 122 on I-75 and the Andersonville Hwy 61 junction.

Race rules and safety: no headsets, earphones, bicycles, baby strollers, roller blades or pets on the course. Runners under 12 must be accompanied by an adult for adult races. An 18:00/mile minimum pace will be enforced and a sweeper will operate on course. Aid stations provide very small cups; runners are encouraged to carry personal water and any necessary medication for insect sensitivity. Special finisher recognition is given to those who complete both distances. Visit the organization's website for the most recent information.
