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!
