100-miler • 50-miler • 50k • Half Marathon • Relay
Sinister 7 is open to solo runners or teams of up to seven and racers have 30 hours to complete the grueling event. The course is split into seven stages, each featuring a geographic and historic highlight of the area. The race's name is inspired by the treacherous Seven Sisters Mountain that looms over much of the course.
We have four distance options in the 2025 race: the 100-mile, the 50-miler (half of leg 4, + legs 5 through 7), the 50k (half of leg 1, half of leg 2, and leg 3), and the Half Marathon (half of leg 1, half of leg 2).
Be sure to check out the Racer Information Package for full race details.
