⏵ Course guide · Indiana winter trail tradition
The HUFF 50K Trail Run has been testing runners against Chain O' Lakes State Park's rolling wooded trails, and the Indiana winter, for years, with a 50K, a 3-person relay, and a shorter one-loop option. I will walk you through what is confirmed about the course and format first, then give you general pacing and fueling guidance for a cold-weather trail race, plus free tools to dial in your own numbers.
HUFF has run annually in mid-to-late December for years, and race calendars list December 19, 2026 for the next edition. This guide could not independently confirm that exact date through the organizer's own channels at the time it was written, so treat December 19 as the expected pattern rather than a locked date, and confirm current registration details with VEEP Races before you commit travel or training plans around it.
These facts come from public race listings and archived organizer pages. Check the current year details, cutoffs, and aid stations before you commit. Race logistics change year to year.
The race runs on well-maintained trails through Chain O' Lakes State Park in northeastern Indiana, described consistently across sources as relatively flat, rolling, wooded terrain, accessible enough for a first-time trail runner but technical enough to reward seasoned ones.
The individual 50K is the headline distance, with a 3-person relay for teams and a shorter One Loop Run of about 10 to 11 miles for runners who want a taste of the course without the full distance. All three share the same Chain O' Lakes trail network.
A mid-to-late December date in northeastern Indiana means potential snow, ice, and genuinely cold temperatures on top of the trail itself. Course descriptions specifically flag possible snow and ice adding to the challenge, so winter footwear and layering decisions matter as much as your training here.
HUFF has drawn 400-plus registrants in past editions and has a track record stretching back well over a decade, with the same Race Director, Mitch Harper, still listed as the primary contact. The organizer's own website has not been visibly updated in some time, so lean on current registration platforms and the race's Facebook page for the freshest details as your race date approaches.
With no published cutoff and generally flat, rolling terrain, pacing here is less about surviving climbs and more about managing cold-weather effort and traction on whatever the trail surface is doing that day.
Snow, ice, and mud can all show up in a mid-to-late December race in northeastern Indiana, and each changes your realistic pace independent of the underlying terrain. Build a pace target off recent training on similar conditions rather than a dry-trail number from earlier in the season.
A finish-time projection built off your training helps you plan when you will likely be out longest in cold conditions, typically the back half of the field on the 50K, so you can layer and fuel accordingly rather than guessing.

Cold weather changes fueling in ways that are easy to underestimate: appetite drops, thirst cues weaken, and your body burns more energy just staying warm.
Aim for roughly 60 to 90 grams of carbohydrate per hour. In cold weather, hunger and thirst signals are unreliable, so set a timer or use aid station passes as fueling checkpoints rather than waiting until you feel like eating or drinking.
If aid stations offer warm fluids, use them, both for hydration and for morale on a cold course. Pack layers you can shed as you warm up and add back if conditions turn, and treat post-race warmth (dry clothes, the race's famous soups) as part of your plan, not an afterthought.

HUFF has run annually in mid-to-late December at Chain O' Lakes State Park in Albion, Indiana for years, historically landing on or near December 19. Race calendars list December 19, 2026 for the next edition, but this guide could not confirm that exact date directly through the organizer's own site, so treat it as the expected pattern and verify current registration and date details before you commit.
The organizer describes the course as accessible enough for a good first-time trail race while still technical enough to reward experienced trail runners, on well-maintained park trails through Chain O' Lakes State Park. Add the wildcard of Indiana winter weather (potential snow, ice, and cold at a mid-to-late December date) and the real challenge here is less about elevation and more about testing yourself against distance, terrain, and the season, as the race's own tagline puts it.
No elevation gain figure is published for the HUFF 50K. Available course descriptions call the terrain relatively flat with rolling wooded trails, so expect Midwest state-park rolling terrain rather than significant sustained climbing.
With a mid-to-late December date, cold-weather fueling and hydration matter as much as carbohydrate math. Aim for roughly 60 to 90 grams of carbohydrate per hour, and remember that cold weather can blunt thirst cues, so stick to a planned hydration schedule rather than drinking only when you feel thirsty. HUFF is known for its post-race food, particularly an array of soups, but plan your on-course fueling independently rather than counting on aid station variety. Build your numbers with the free ultra fueling calculator before race day.
No cutoff times are published in the sources available for this guide. Confirm current cutoff information directly with VEEP Races or on the current year's registration page before you build your pacing plan.
The One Loop Run (about 10 to 11 miles) and the 3-person 50K relay both give newer trail runners or teams a lower-commitment way into the event. For a first solo 50K, the organizer's own framing, an easy enough course for a good first-time trail race, plus a long track record and an experienced volunteer crew, makes HUFF a reasonable choice, as long as you come prepared for cold-weather race conditions in mid-to-late December.
