About

Sorta Mountain Stage Race takes place in Borden, Indiana, on September 13, 2026. Four trail formats are on the schedule: a 50K (31 miles) described as an 18-mile plus 13.1-mile combination, the Ultimate 18 (about 18 miles), a trail half marathon (13.1 miles) and a 5-mile. The 50K is therefore built as a stage-style effort, with the 18-mile and the half marathon run back to back.

That structure changes how you should prepare. If you go for the 50K, practice a long run followed by a second run with only a short break, so your body knows how to restart on tired legs. The Ultimate 18 and the half marathon are strong choices for trail runners wanting a longer race without going full ultra, and the 5-mile is the option for newer runners or a family member joining you. A 12- to 16-week plan with weekly hill work fits all four formats; only the 50K needs the extra double-run rehearsals.
