Rock ’N The Knob Trail Challenge
September 11, 2027 at Blue Knob All‑Season Resort.
Allegheny Trailrunners is pleased to announce that the sleepy giant who took a nap last year has awakened.
Rock ’N The Knob Trail Challenge returns in all its terrible glory on September 11 at Blue Knob All‑Season Resort.
Back are the nightmare courses that test all who dare try:
The 10K packs a wallop, featuring Throat Punch - one of the most infamous climbs in Pennsylvania trail racing.
The Half Marathon crests the Alleghenies’ northernmost 3,000-foot peak and tangles with the wonderfully ominous Euros (“The East Wind”), which seeks out the unworthy and plucks them from the earth.
The 50K exists for one reason only: to be one of the baddest, meanest trail experiences in the Mid‑Atlantic.
Registration opens in February.
You’ve been warned.
Course Takeaways
10K course
The 10K course may be the most challenging 10K in PA* (*based on the fastest and average finish times.) The 10K features trails like Lost Porcupine, Code-Red, Tree-odge, Devils Hairpin, Throat Punch Hill and Soul Sucker Slopes! Two major climbs give you nearly 1500 feet of climbing. There is one aid station at the base of the first climb called Throat Punch Hill at 3.7 miles. [No pacers, drop bags, or crew.]
There is no cutoff at the one and only aid station, however all participants need to finish the race in 7 hours (5pm).
Rated #14 as the Toughest Trail 10Ks in the Northeast by Trails Collective and #1 Toughest in Pennsylvania.
10K: 1496 feet of climb in 6.2 miles is 241 feet of climbing per mile [“back-half” is 390 feet/mile]

Half-Marathon
In 2019, we added a half-marathon course! Get ready - this half-marathon is a doozy. We took our marathon course and cutting it in half but leaving in more than half of the challenges and suffering in with over 3500 feet of climbing on the 13.51 mile course! The half features some gnarly sections like Blister Blaster, Teal is Real up Deep Hollow Notch, I’ll Nettle Do This Again and I Need a Sherpa!
Rated in the Top 10 (#8 ) among the Toughest Trail Half-Marathons in the Northeast by Trails Collective.
