That Dam Hill

That Dam Hill offers a unique challenge for athletes, being London's only ultra marathon timed race, and it's a Boston Marathon Qualifier! Operated entirely by dedicated volunteers, 100% of net proceeds are directed to support cancer research, with an impressive $1.2 million raised by Dunn with Cancer. Beyond the race, our charitable partners benefit by independently raising funds for their causes. Despite the name, don't be intimidated—the hill is more of a molehill, making it a perfect opportunity for runners seeking a certified and spectator-friendly marathon experience.
