About the race
Bold Coast Bash is a trail running event held in Cutler, ME offering two distances.
Distances
- 50K Ultra three laps of a figure 8 course, each lap about 16.7 km (10.4 miles)
- 10.5 Mile Fun Run one lap of the figure 8 course
The course runs along the Bold Coast cliffs and includes single track, inland sections with mud and rocks, bog bridging, exposed roots, and unfenced cliff tops. Many surfaces can be slippery or unstable; course turns and junctions are marked with blue surveyor’s flags. There is a single aid area at the Start/Finish; there are no aid stations on the course so runners must be self supporting. Expect each lap to take between two and four hours.
Mandatory equipment is checked at the start and before every lap and includes a windproof or waterproof jacket, warm mid layer, warm head covering, warm gloves, foil blanket, whistle, at least 200 calories of instant energy, and a headlamp for the third lap. Cell coverage is spotty; live tracking is available via a timing app but requires cell service and carrying a phone.
Entrants are capped to protect fragile ecosystems. Registration opens 1 August 2026 at 7:00am and closes 5 November 2026 at 11:59pm ET. There is no day of registration and bib pick up is required. Entry fee is $45. The event does not offer refunds; entries may be deferred to the next year at 75 percent of the fee if done by 31 October.
