Prepare for an unparalleled winter challenge at the Frozen Heart 900, a unique 15-hour (900-minute) "fatass" style ultra-endurance event hosted by the CT Trailmixers. Set for February 7, 2026, in Rockfall, CT, this race offers a true test of grit against the New England winter, where typical race day conditions often see highs around 38F and lows near 19F, with a slight chance of precipitation. Embrace the raw beauty of the season on the challenging 2.2-mile Camille's Way Blue Blazed trail. The course, described as hilly with an elevation gain of approximately 2500-7500 feet over 50 miles and featuring rocks, roots, and ruts, will push your limits with its "washing machine" format, alternating between clockwise and counter-clockwise loops.

What makes the Frozen Heart 900 truly stand out is its commitment to a no-frills, unsupported experience. This means no entry fees, no awards, and no traditional aid stations, fostering an environment where self-reliance and camaraderie are paramount. However, runners will find comfort at the Connecticut Forest & Park Association (CFPA) headquarters, which serves as the race hub. Here, a heated meeting room, full kitchen, and real bathrooms provide a welcome respite from the cold, along with access to running water and potential s'mores over a Solo Stove. Participants are responsible for tracking their own laps on this multiple-loop course, and headlamps are essential for running after sundown.

This is an event for those who relish long days, cold weather, and good company, designed by runners for runners seeking a winter ultra when other options are scarce. Limited parking necessitates carpooling, and while the spirit is unsupported, the sense of community among those brave enough to tackle the Frozen Heart 900 is its own reward.
