Prepare yourself for an unforgettable trail running experience steeped in local lore. The Fall Creek Beast is not just any race; it's a tribute to a mythical creature from Idaho’s past, said to have terrorized Swan Valley with its luminous scales and deadly venom back in 1868.
The Race Course:
This challenging event offers two distances that cater to both seasoned ultrarunners and those seeking an intense half marathon experience. Both courses feature a mix of singletrack trails, double-track paths, gravel roads, and significant elevation gains. The centerpiece is the formidable Prospector Peak, which stands as a daunting obstacle for all participants.
50K Course:
Starting at 6:00 AM from Rainbow Valley Ranch on Fall Creek Road, runners will face over 6,000 feet of climbing across three aid station checkpoints before reaching the finish line by 3:00 PM. The route circles through Pritchard Creek and Horse Creek loops before culminating in a grueling ascent to Prospector Peak.
13.1M Course:
For those looking for a more compact yet equally formidable challenge, the half marathon begins at 9:00 AM with nearly 2,700 feet of elevation gain leading up to Prospector Peak by the same cutoff time. This course includes three aid station stops and features an iconic turnaround point near Rainbow Valley Ranch.
Both courses are meticulously marked with reflective flagging for easy navigation in varying weather conditions. The race organizers ensure that every participant receives comprehensive support, making this event accessible while maintaining its reputation as a demanding test of skill and endurance.
