Overview

The Prairie Spirit 50 km Trail Ultra Race, first run in 2017, will next take place on March 27, 2027. This 50 km trail race follows an out-and-back course from Ottawa, KS, primarily on a crushed limestone trail, with asphalt paths through towns.

With 52 finishers at its latest edition in 2026, the race has a field bigger than 59% of 50k races, yet smaller than 40% of its 2818 peers. Runners have 28 hours to complete the 50 km, which is a generous time limit for the distance.
