Frosty Bottom Update:
The 2025 Frosty Bottom Short and Long is Cancelled.
After visiting course trails this morning, they continue to confirm to be very unsafe. This is a first and sad news for all, but cancelling the 2025 edition of the Frosty Bottom is a must.
With forecast showing more rain and higher temps (40 degrees) on the horizon, trail conditions are only going to get worse. Safety for you (frost bottom participates) and additional trail users is our top priority.
For all those currently registered, please watch your emails closely for information regarding the options for future race entries and/or how to proceed.
​
On behalf of Chain Reaction Cycles, we thank you in advance for your patience and understanding.
Frosty Bottom Update:
We have been closely monitoring trail conditions along the course profile. Unfortunately, it is glare ice on most sections of the course. Though a safe and injury free event for all participants and other trail users cannot be guaranteed, our first priority is safety. As of current, the trail conditions show higher risk than reward.
Please continue to watch Facebook, Instagram, and email for updates.
Thank you
Frosty News:
Course could be very challenging to mark course this year if we don't get more snow.
