REVEL Big Bear Marathon distinguishes itself with its dramatic descent from the heights of the San Bernardino Mountains down to the town of Redlands. This downhill course follows a gradual yet significant drop that tests a runner’s quads while rewarding them with breathtaking vistas around every bend. As part of the REVEL series, known for their downhill races, Big Bear stands out due to its scenic mountain backdrop and cool November weather. A staggering 40.5% of finishers historically qualify for Boston — a testament to the course's speed. The PR Score of 106.02/100 suggests that conditions here are about as favorable as it gets for those chasing a qualifying time. However, it's not without its challenges. The steep descent requires strategic muscle training and pacing to prevent a blowout in the latter stages. From the start in the chill of the mountains to the warmer valley finish, runners encounter varied conditions. The early miles are exhilaratingly fast due to the descent but managing this speed is crucial to avoid fatigue. Aid stations are well-placed, but hydration and nutrition strategies need to account for the elevation drop and potential temperature changes. The community in Redlands is supportive, with locals often turning out to cheer runners through the final miles. Though not a race with a long historical pedigree, its reputation is growing among those who appreciate a course designed for speed and the unique challenges of a downhill marathon.
