Rio Frio 5k on Ice

Race Information

One of America’s most unique 5k races kicks off at 10:00 a.m. on Saturday, January 25th, 2025. This spectacular race is conducted entirely on the frozen Rio Grande. Don't fret; a thin layer of snow offers traction while you take in the majestic views of the San Juan’s to the West and Sangre de Cristo’s to the East from the heart of the San Luis Valley!

Runner's World Magazine named this race one of three "editor's picks" for running enthusiasts for 2015. Chip timing and unique “ice-themed” awards enhance this special race for runners of all abilities.

Backup Racecourse

In the 11-year history of this race, we have had to use an alternate racecourse three times due to unsafe ice depth. However, we have an alternate racecourse that provides a fun and unique "5k on Ice" experience using the 30-acre pond at Blanca Vista Park and a portion of the levee trail system.

Footwear Recommendations

Participants are advised to wear running shoes with microspikes or other shoes that provide extra tread for better traction on snow and ice.

Race Packet Pickup

Race bibs, chips, and swag bags are available for pickup from 6:00 p.m. to 7:30 p.m. at Knee Knockers Bar & Grill on Friday, January 24th, 2025, and from 8:00 a.m. to 9:30 a.m. at the Alamosa Senior Citizens Center on race day.
