Rio Frio 5k on Ice

One of America’s most unique 5k races kicks off at 10:00 a.m. Saturday, January 24th, 2026. This spectacular 5k race is conducted entirely on the frozen Rio Grande. Have you ever run on a frozen river? 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 four times due to unsafe ice depth on the Rio Grande. We have an alternate racecourse as a backup that still provides for a fun and unique "5k on Ice" experience. We utilize the 30-acre pond at Blanca Vista Park and a portion of levee trail system for the 5k. So regardless, you will take in great view…
