⏵ Course guide · Coastal Maine ultra
Blue Hill Mountain Trail Fest sends the 50K field up and down a 934-foot coastal Maine summit seven separate times, on a figure-eight loop through wildflower fields, dense forest, and views out over Hancock County. I will walk you through the repeated-climb format first, then give you a pacing and fueling plan built for cumulative fatigue rather than one big mountain day. There are free calculators along the way to dial in your own numbers.
These facts come from the official race registration page and public race listings. Check the current year details, cutoffs, and aid stations before you commit. Race logistics change year to year.
The 50K runs a figure-eight loop course seven times, and the 25K runs the same loop three times. Every lap climbs Blue Hill Mountain, so this is a race decided by how well you manage repetition, not by how you handle one defining climb.
Each loop opens through open wildflower fields before dropping into dense, technical forested singletrack on the way up the mountain. The footing shifts fast between the two: easy, grassy ground gives way to roots and uneven trail with almost no warning. Early loops in daylight are the time to learn exactly where those transitions are, because you will be running them again in different light and with tired legs later in the day.
The payoff on every loop is the summit of Blue Hill Mountain, with views out over Hancock County and the coast. It is a real reward the first couple of times. By loop five or six it is just another climb, and that mental shift, from scenic overlook to repetitive obstacle, is part of what this race tests. Manage your head as much as your legs.
Because every loop returns to the start-finish area, you get frequent access to your own supplies and the race’s aid station, which famously serves whoopie pies, a nice regional touch but not a fueling strategy. Use the frequent aid access to your advantage: stage exactly what you need at each loop instead of overloading your vest for seven laps at once.
Seven loops in a 10-hour window means roughly 1 hour 25 minutes per loop on average, but your early loops should run faster than that, not slower, to bank the buffer your legs will need later.
The instinct on a fresh loop one is to push, since the climb feels manageable and the views are new. Resist it. A grade-adjusted pace target for the climb gives you an honest number for what you can actually repeat seven times, not just once. Runners who blow up here almost always ran loop one or two too hard and paid for it on loop five.
Because the course is loop-based, you get real data after loop one or two: use it. A vert-aware finish prediction built off your actual early splits, extrapolated across all seven loops, is far more honest than any flat-course time you might bring in from a road 50K. Check that projection against the 10-hour cutoff early enough to adjust your effort, not after loop five when adjusting is hard.

A 5 AM start means you begin in the cool of the morning and finish, if you are out for the full 10 hours, in the heat of the afternoon. Plan your fueling and sodium to shift as the day warms up.
Aim for roughly 60 to 90 grams of carbohydrate per hour, and use the frequent aid access at the start-finish to keep your intake steady rather than front-loading or skipping loops. Whoopie pies are a fun bonus at the aid station, not a substitute for a real per-hour carbohydrate plan.
Early loops in the cooler morning can sit toward the lower end of 300 to 500 mg of sodium per liter of fluid. As the day heats up through the middle and later loops, especially through the exposed wildflower field sections, push that toward 500 to 700 mg per liter. Adjust loop by loop instead of setting one number for the whole race.

It is harder than a 934-foot summit sounds. The 50K climbs Blue Hill Mountain seven separate times across a figure-eight loop course, mixing wildflower fields, dense technical forest, and coastal vistas from the top. There is no official total elevation figure published, but seven trips up and down the same mountain adds up fast, especially with a 10-hour cutoff and a field capped at 50 runners for a reason. Repetition, not one big climb, is what wears you down here.
Blue Hill Mountain itself tops out at 934 feet, and the 50K climbs it on all seven of its figure-eight loops, so the total gain stacks up well past what the modest summit height implies. The 25K covers three of those same loops. Treat every loop as a real climb, not a warm-up, because by loop five or six your legs will disagree with how short 934 feet sounded on paper.
Early August in coastal Maine can run warm and humid even with the ocean nearby, and a 5 AM start means you will be climbing into the heat of the day by the later loops. Aim for roughly 60 to 90 grams of carbohydrate per hour, and keep sodium in the 300 to 700 mg per liter range, leaning higher if the day turns hot and sticky. The race famously serves whoopie pies at the aid station, which is a fine bonus but should not be your fueling plan. Build your numbers with the free ultra fueling calculator before race day.
The 50K has a 10-hour overall cutoff from its 5 AM start. The 25K gets 5 hours, the 10K gets 3 hours, and the 5K gets 2 hours. With seven loops to complete on the 50K, that works out to a bit under 1 hour 25 minutes per loop on average, so a slow start eats into your buffer for every loop that follows.
The figure-eight course mixes open wildflower fields, dense and technical forested singletrack, and coastal views from the summit of Blue Hill Mountain looking out over Hancock County. Expect uneven, root-heavy footing in the wooded sections and exposed, sun-baked stretches through the fields. Early August weather on the Maine coast is usually mild but can turn warm and humid, and the repeated loops mean you will experience the same terrain in changing light and heat across the day.
The repeated-loop format is actually a good one for a first ultra: you pass through the start-finish area often, so crew access, drop bags, and mental math are simpler than a point-to-point. The challenge is purely physical, seven ascents of the same climb, and that repetition rewards even pacing over early enthusiasm. If you have trained on rolling, technical New England singletrack and you respect the cumulative fatigue of seven loops, the 10-hour cutoff gives a well-prepared first-timer real room to finish.
