Rio Frio on Ice 5K

Registration for the 2025 Rio Frio 5k is NOW OPEN!

***Unfortunately, due to unseasonably warm weather, neither the Rio Grande River nor the Blanca Vista Pond will be able to support our Annual 5k On Ice. As such, the race course for this year's 5K Race will take place along the City of Alamosa's Levee Trail System. If you have any questions, please do not hesitate to contact the Alamosa Family Recreation Center at 719-589-2105

2025 Rio Frio 5k Race Course

One of America’s most unique 5k races kicks off at 10:00am on Saturday, January 25th, 2025. This spectacular 5k race is conducted on the frozen Rio Grande River!

A guaranteed shirt can only be promised if registration is complete by January 5th at 11:59pm.

Race Packet Pickup: This is a chip-timed race. Race bibs, chips, and swag bags are available for pickup from 6:00 pm to 7:30 pm at Kneeknocker Bar & Grill (500 Cottonwood Dr.)on Friday, Jan. 24th, 2025, and from 8:00 am to 9:30 am at the Alamosa Senior Citizens Center the day of the race. 

Backup Racecourse: In the 10-year history of this race, we have had to use an alternate racecourse three 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!
