Tucson Trail Runners (TTR) is a trail/ultra running group that focuses on (mostly) long-distance trail runs on public lands in all five mountain ranges surrounding Tucson, Arizona. The average distance for our runs is 15 to 20 miles with many in the 20+ distance range, although shorter route options are often available. TTR meets almost weekly on Sundays from September through the beginning of July. Many of the regular participants are ultramarathon runners who use the series to train for longer runs and races, but there are an array of ages, genders, and ability levels. If you are interested in running with TTR, please read The Series to determine if your experience matches the difficulty of our runs.
