Calico Trail Run

The Calico Trail Run is held in Yermo, California, on January 24, 2027, with both distances leaving together at 7 a.m.: a 50K (31 miles) and a 30K (18.6 miles). Two long trail options and a single start make for a simple race morning, with no shorter distances to plan around.

Trail running at these lengths asks for different habits than road racing. Effort matters more than pace, footing decides your splits, and a 7 a.m. start means eating properly before the sun is fully up. Carrying your own fluid is the safe default on distances like these. The 30K suits a runner who already handles a half marathon comfortably and wants a first taste of trail ultra pacing; the 50K needs several months of building, back-to-back weekend long runs, and a fueling routine you have already tested at effort.
