Registration and pre-race details

The Frostbite Series will take place at its usual short and long course series of races starting at the Forest Park Visitors Center. We strongly encourage participants to preregister as limited race day registrations will be available. For those who cannot compete in the entire series, single race registrations are also available.

The long and short course series will each have its own set of starting times. The start for the long race will begin at 8:00 a.m. The start for short races will begin at 8:15 a.m.  Bib numbers can be picked up prior to race day - see below. Bibs should be kept and used for the duration of the series. Replacement bibs will be available should you lose/forget yours.
