Terrain Race is a United States obstacle and mud 5K series operated by EventLab, which also runs Muddy Dash, Bubble Run, FoamGlow, Blacklight Run and The Color Run on the same platform. The course is a 5K over rugged terrain with mud pits and obstacles, positioned by the operator as a step up in difficulty from its Muddy Dash sibling. Entry is sold in two tiers: a Value registration including race bib, race tee, finisher medal, festival access and course photos, and a VIP registration adding a premium tech tee, swag bag, early wave start, VIP tent, reserved gear check and a finisher patch. The festival village opens roughly two hours before the first wave, and the events are billed as family-friendly with all ages welcome.
