10 Vermont Trail Races Worth Adding to Your Calendar
Vermont doesn't shout about itself. The state has no marquee city marathon, no massive sponsor-driven race series, and no shortage of mud. What it does have is some of the most compelling trail running terrain in the northeastern United States, a tight-knit racing community, and a calendar that rewards runners who plan ahead. Whether you're chasing your first trail finish line or hunting for something that'll genuinely break you, Vermont delivers.
The interest in off-road racing is accelerating across the board. Why the Half Marathon Is the Fastest-Growing Race Distance in 2026 tracks how runner demographics are shifting, and trail events are pulling in a meaningful share of that growth. Vermont is quietly positioned at the center of it.
Why Vermont Works for Trail Runners
The geography here is genuinely varied within a compact area. You can run ridge lines above 4,000 feet in the morning and be on root-laced forest singletrack by afternoon. The Green Mountains run the length of the state, and the Long Trail. America's oldest long-distance hiking path. cuts through the kind of terrain that makes trail runners stop mid-race to look around.
Vermont also has covered bridges, river valleys, and working farm roads that occasionally appear mid-race in ways that feel almost staged. They're not. That's just what running here looks like.
The community culture is a real differentiator. These races don't feel like logistics operations. You're more likely to get a homemade soup at the finish line than a branded recovery tent. That low-key atmosphere is exactly what draws runners who've grown tired of large race series and their $200 entry fees and corrals numbered like airport terminals.
A Practical Note on Registration
If you're traveling from out of state, treat Vermont trail race registration the same way you'd treat booking a flight at peak season. Many of these events cap at 200 to 500 runners, and several sell out within days of opening. Set calendar reminders. Most races open registration between January and March for summer and fall events.
Planning your race weekend around nutrition is also worth thinking through before you commit to travel. How to Time Your Meals Around Your Workouts covers the practical timing strategies that matter most when you're racing in unfamiliar territory and don't have your usual pre-run routine on hand.
The 10 Races
1. Vermont 100 Endurance Race
The Vermont 100 is one of the oldest 100-mile trail and road ultras in the country, run every July through the hills of South Woodstock. The course mixes dirt roads, horse trails, and forest paths across a genuinely demanding 100-mile loop. It's part of the Grand Slam of Ultrarunning, which means the field includes serious ultra veterans. Entry fees typically run around $375. This one fills fast, and for good reason.
2. Stowe 8-Miler
Don't let the distance fool you. The Stowe 8-Miler punches well above its weight with sustained climbing on the trails around Stowe Mountain Resort. It's an ideal entry point for runners transitioning from road to trail, and the post-race setup in Stowe village is hard to beat. Entry is usually priced around $55 to $70 depending on registration timing.
3. Kingdom Trail Endurance Run
Held in the Northeast Kingdom around Burke Mountain, this race uses some of the best mountain bike singletrack in New England. The trail network is meticulously maintained, which means you're getting fast, flowing terrain rather than the ankle-testing root mazes common elsewhere. Distances range from 25K to 50K. It's approachable for newer trail runners while still offering enough elevation to make the longer distance meaningful.
4. Covered Bridges Half Marathon (Trail Edition)
This isn't your standard half marathon. The trail version routes through rural Woodstock and Quechee, crossing several of Vermont's iconic covered bridges along the way. The mix of paved farm roads and dirt path makes it genuinely accessible for runners still building trail-specific strength. It's a strong option if you're looking for a scenic event that doesn't require technical trail experience.
5. Pittsfield Peaks Trail Race
Run out of Pittsfield, Vermont, this race is associated with the same community that puts on Spartan's Vermont venue. but the trail race itself is an independent, low-key event with a completely different feel. Expect steep climbs, ridge views, and a finish line that feels earned. The 10-mile and 25-mile options make it accessible across experience levels.
6. Mad Marathon and Trail Series
The Mad River Valley hosts this summer trail series, with events ranging from 5K to marathon distance. The valley setting is spectacular, and the race organization is known for being genuinely runner-focused rather than sponsor-driven. If you're traveling with a mixed group where not everyone wants to run 30 miles through the mountains, this series has something for everyone on the same weekend.
7. Wilmington Trail Race
A shorter, fast event in the southern Green Mountains near Mount Snow, the Wilmington Trail Race draws a mix of competitive trail runners and locals looking for a hard Saturday morning. The course is mostly singletrack with enough climb to make you work. Entry fees are modest, typically under $50, which reflects the grassroots character of the event.
8. Green Mountain Dirty Duo
This two-day format is worth highlighting specifically because it changes the way you approach pacing. Day one and day two run separate courses through the Green Mountains, and cumulative time determines overall placement. It's a format that rewards smart runners over pure speed merchants, and it gives you a full weekend of trail running without committing to a single ultra-distance effort. Expect to budget around $120 to $150 for the combined entry.
9. Catamount Ultra
Held at Catamount Outdoor Family Center in Williston, the Catamount Ultra offers 25K and 50K options on groomed trail systems that are well-marked and reliably maintained. It's one of the more beginner-friendly longer-distance options in the state, with aid stations that are well-stocked and volunteers who seem to genuinely enjoy being there. A good first ultra choice for runners ready to step up from half-marathon trail distances.
10. Mount Mansfield Climb
Vermont's highest peak, Mount Mansfield tops out at 4,393 feet, and this race goes up it. The climb is relentless, the views at the top are the kind that justify the entry fee on their own, and the descent requires your full attention. It's not a high-volume event, which keeps the experience intimate. If you want one race on this list that will test your mountain running instincts specifically, this is it.
What to Know Before You Go
Vermont trail conditions vary significantly by season. Summer races are mostly runnable but can be humid and muddy after rain. Fall races offer the best foliage and firmer ground but cooler temperatures at elevation. Spring events, while rare, often mean wet, soft trails that test your gear choices as much as your fitness.
Recovery after back-to-back training blocks or a demanding trail race matters more than most runners acknowledge. The research on nutrition for active recovery has sharpened considerably in recent years. Anti-Inflammatory Foods for Athletes: What the Evidence Shows is worth reading before you plan your post-race meals, particularly if you're racing multiple weekends in a season.
Trail running in Vermont also connects to a broader ultra scene that's growing across the Northeast and beyond. What's Up in Ultra This Weekend: May 2026 Roundup tracks what's happening across the region if you're looking to stack multiple events into a travel plan.
The Case for Making the Trip
You can train for a Vermont trail race anywhere. But you can't replicate what it feels like to run through a covered bridge at mile nine, or to summit a Green Mountain ridge with a field of 200 other runners who've all made the same choice to be there. These aren't events built around spectator counts or Instagram moments. They're built around the running.
That's what makes Vermont's trail scene worth the trip. Pick one race on this list that matches where you are as a runner right now, register early, and build your year around it.
