Tucson Trail Runners (TTR) is a running group that primarily focuses on long-distance trail runs on public lands in all five mountain ranges surrounding Tucson, Arizona. The lengths of our runs vary from 10 to 30 miles with many in the 20+ mile range, although shorter route options are nearly always available. TTR meets almost weekly, generally on Sundays, from September through the end of May. Many of the regular participants are ultramarathon runners who use the series to train for longer runs and races, but this is not a rule and our group strives to be diverse in age, running purpose, and ability. If you are interested in running with TTR, please read The Series to determine whether your notion of a "good time" is similar groups.
