New Hampshire’s Mount Washington Valley will host one of the Northeast’s most unique and challenging events this April.

The Tuckerman Inferno – a grueling, single-day pentathlon that has gained a reputation for being one of the Northeast’s toughest events – will be held Saturday, April 13.

The event has been held each year since 2000, and it raises money for the Friends of Tuckerman Ravine.

During the Inferno, participants must run, kayak, bike, hike and either ski or snowboard.

The race begins with an 8.3-mile run that features 600 feet of climbing. Competitors then kayak 5.5 miles of whitewater featuring Class II rapids. After the kayaking section comes a grueling 18.2-mile bike leg that includes roughly 2,000 feet of climbing. Racers then hike roughly three miles of difficult terrain with more than 2,200 feet of climbing. They then finish the race by skiing or snowboarding a giant slalom course on the Northeast’s most iconic slope – Tuckerman Ravine.

Participants can take on the Tuckerman Inferno course by themselves, or they can do it as part of a relay team, with team members tackling different sections of the course.
