Rio Frio 5k on Ice

❄️ Event Overview

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

• History: 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.
• Backup Option: We have an alternate racecourse as a backup that still provides for a fun and unique "5k on Ice" experience.
• Location: We utilize the 30-acre pond at Blanca Vista Park and a portion of levee trail system for the 5k.
• Scenery: Regardless, you will take in great views and run on ice/snow!

👟 Footwear

• Recommendations: Participants wear a variety of footwear to run fast and to stay safe.
• Ideal Shoes: We recommend running shoes with microspikes or a DIY version of microspikes.
• Helpful Resource: Here is a video showing you how to improve traction for snow and ice on your own running shoes: Youtube Video
• Alternative Options: If no traction device, hiking boots or other shoes that provide a little extra tread are recommended!
