One of America’s most unique 5k races kicks off at 10:00 a.m. Saturday, January 25th, 2025. 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.
