From the Organizer
One of America’s most unique 5k races kicks off at 10:00 a.m. Saturday, January 30th, 2027. This spectacular 5k race is conducted entirely on the frozen Rio Grande when conditions allow. 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 12-year history of this race, we have had to use an alternate racecourse five 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 views and run on ice/snow!
Footwear: Participants wear a variety of footwear to run fast and to stay safe. We recommend running shoes with microspikes or a DIY version of microspikes. Here is a video showing you how to improve traction for snow and ice on your own running shoes if no traction device, hiking boots or other shoes that provide a little extra tread are recommended!
Race Packet Pickup: This is a chip-timed race. 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, Jan. 29th, 2027, and from 8:00 a.m. to 9:30 a.m. at the Alamosa Senior Citizens Center the day of the race.
