⏵ Course guide · North Alabama rocky 50K
Mountain Mist sends its field through Monte Sano State Park and the Land Trust of North Alabama on extremely rocky mountain trail, mud, and creek crossings, 3,872 feet of climbing packed into roughly 31 miles, including a climb steep enough to demand your hands. I will walk you through the terrain and the strict checkpoint cutoffs first, then give you a pacing and fueling plan built for technical Alabama trail, plus free tools to dial in your own numbers.
These facts come from the official Huntsville Track Club event page and the UltraSignup registration page. Check the current year details, cutoffs, and entry deadlines before you commit. Race logistics change year to year.
The course runs through Monte Sano State Park and the Land Trust of North Alabama, carrying 3,872 feet of climbing over extremely rocky mountain trail, mud, and creek crossings.
One climb on the course is steep and technical enough that the official course description calls out the need to use your upper body to get up it. Practice scrambling on steep, rocky terrain before race day, not just climbing on your legs, because this section is a different kind of effort than the rest of the course.
Beyond the marquee climb, the course threads rock walls, stone cuts, and sinkholes, terrain that rewards careful foot placement over raw speed. The race finishes through McKay Hollow, a fitting close to a course built almost entirely on technical footing rather than smooth trail.
Mountain Mist enforces four time limits along the course, not just an overall finish cutoff: Mile 15.5, Mile 20.9, Mile 24.9, and the Mile 31 finish. Runners who miss a checkpoint cutoff are removed from the course, no exceptions, so treat every checkpoint as its own deadline rather than budgeting only for the final finish time.
With checkpoint cutoffs at Mile 15.5, 20.9, 24.9, and the Mile 31 finish, Mountain Mist asks you to manage pace against four deadlines, not one, on genuinely technical footing.
Extremely rocky mountain trail slows every runner down more than the raw mileage suggests, so a road or even a smooth-trail pace target will mislead you badly here. A grade-adjusted pace approach gives you an honest read on what effort each checkpoint segment actually demands, including the hands-and-feet climb.
Because Mountain Mist enforces four separate time limits, your pacing plan needs four checkpoints, not one. A vert-aware finish prediction, checked against each individual checkpoint cutoff rather than just the overall 8 hour 30 minute finish, tells you honestly whether you have real margin or are running right at the edge.

Late January in North Alabama usually runs cool, so heat is rarely the limiting factor here. The rocky, technical terrain burns energy fast even without hot weather, so do not shortcut your carbohydrate plan.
Aim for roughly 60 to 90 grams of carbohydrate per hour. Technical, rocky footing costs more energy per mile than smooth trail, even at the same pace, so treat your fueling plan as seriously here as you would on a longer, flatter race.
Sodium in the 300 to 700 mg per liter range covers most runners, and in cool late-January conditions you can likely lean toward the lower end unless the forecast runs unusually warm. Cool weather still means real sweat loss on a course this technical and this climb-heavy, so do not skip hydration just because it does not feel hot.

Mountain Mist is a genuinely tough 50K through Monte Sano State Park and the Land Trust of North Alabama, with 3,872 feet of climbing packed into about 31 miles of extremely rocky mountain trail, mud, and creek crossings. The course includes a vertical climb steep enough that you will need to use your upper body to get up it, plus rock walls, stone cuts, and sinkholes along the way, finishing through McKay Hollow. Four strictly enforced checkpoint cutoffs, the last at 8 hours 30 minutes for the finish, mean this is not a course to show up undertrained on.
The course carries 3,872 feet of climbing over roughly 31 miles, and the terrain makes every foot of it earn its keep. Expect extremely rocky mountain trails, mud, and creek crossings throughout, plus one climb steep and technical enough that runners use their hands and upper body to get up it. This is not a smooth, runnable vert profile. The rock and technical footing slow you down as much as the raw elevation numbers suggest, sometimes more.
With an 8 hour 30 minute overall cutoff and rocky, technical terrain the whole way, most finishers are on course for somewhere between 5 and 8.5 hours. Aim for roughly 60 to 90 grams of carbohydrate per hour, and sodium in the 300 to 700 mg per liter range. Late January in North Alabama usually runs cool, so hydration needs may be lower than a summer race, but do not skip your carbohydrate plan just because the heat is not a factor. The rocky terrain alone will burn through your energy stores.
Mountain Mist runs four strictly enforced time limits: Mile 15.5 at Oak Park Ball Fields in 3 hours 40 minutes (about 14:12 per mile pace), Mile 20.9 at the Land Trust Aid Station in 5 hours 15 minutes (about 15:04 pace), Mile 24.9 at Trough Springs Aid Station on Monte Sano Blvd in 6 hours 30 minutes (about 15:40 pace), and Mile 31 at Monte Sano Lodge, the finish, in 8 hours 30 minutes (about 16:27 pace). Runners who do not make a checkpoint in the allowed time are removed from the course, no exceptions, so build real margin into your pacing plan rather than targeting the cutoff paces exactly.
The field is capped at 525 runners, and registration closes completely on January 17, with no exceptions: no refunds, no race-day registration, and no transfers. The Huntsville Track Club runs the event, and given the firm entry rules, register early and confirm your plans well before the cutoff date rather than counting on a late or race-day entry.
The strictly enforced checkpoint cutoffs and the genuinely rocky, technical terrain, including a climb that requires upper body strength, make Mountain Mist a demanding choice for a first ultra rather than an easy one. It rewards runners who have trained specifically for rocky, technical footing and steep climbing, not just base mileage. If you have that kind of trail experience, the well-organized checkpoints and the Huntsville Track Club's decades of running this event give you a fair, honest test. If you are brand new to trail ultras, treat the pace requirements at each checkpoint seriously before you commit.
