The Race

The Course

Bring your coat, cooler and perseverance because we have brought a very popular event back to life! Located near downtown Fort Worth between the botanical gardens and Clear Fork Trinity River lies beautiful Trinity Park and Trinity Trails - the staging area for El Frio 50 & El Fuego 50. These no frills races are part of a two part series designed to be run at opposite times of the year (winter & summer). The course showcases some of the best views of the Fort Worth skyline while winding along the river and through old growth oak trees. Participants will enjoy downtown views, music, food, and a flat, fast 3.1 mile loop course consisting of mostly pavement with a small portion of gravel road.


If you are looking for a challenge that is as cold as the Frio River then this unique experience is for you. This race was designed on a course for PRs or to break into the ultra scene!
