Overview
The Snowdrop Ultra 55 Hour Race offers a 50-mile split as part of a fixed-time event, rather than a fixed-distance race. This event takes place in Sugar Land, TX, on a road loop less than 3 miles long.
With 10 editions run since 2015, this race has grown to host 150 finishers in its most recent running in 2025. This makes it larger than 83% of 50-mile races, placing it among the biggest fields for this distance category. The course is a 0.7-mile loop on crushed granite and pavement, which runners repeat for the duration of their chosen event.
