28th Annual Mickelson Trail Trek

The Fall Mickelson Trail Trek follows one of the most iconic rail-trails in the country: the George S. Mickelson Trail, winding 109 miles through the very heart of South Dakota’s Black Hills. Inducted into the National Rail-Trail Hall of Fame in 2010, the trail is built on a historic railroad grade and surfaced with smooth crushed limestone, it offers a front-row seat to landscapes you simply can’t see from the highway — quiet pine forests, granite outcroppings, wide open meadows, and hidden mountain valleys.

In autumn, the trail comes alive with golden aspens, deep green pines, and crisp mountain air, making it one of the most beautiful times of year to ride. Wildlife is more active, the crowds are thinner, and every overlook feels like a private postcard.

Along the way, riders pass through four cool, echoing railroad tunnels and roll across more than 100 towering trestle bridges, many of them perched high above creeks, canyons, and forested ravines. Each mile tells a story of the region’s mining past, railroad heritage, and wild beauty, creating a ride that feels as much like a journey through history as it does a cycling adventure.

The trail’s gentle railroad grade makes most of the route comfortably rideable, but the Black Hills still deliver their signature challenge. The climb toward Dumont — including the long, steady stretch from Rochford — rewards riders with sweeping views and a deep sense of accomplishment at the highest point on the trail.

This is more than a bike ride — it’s a chance to experience South Dakota’s most legendary trail at its most spectacular time of year.

Riders will immerse themselves in the jaw-dropping beauty of the Black Hills as they pedal through rolling valleys, cool pine forests, historic railroad tunnels, and charming old mining towns. The Fall Mickelson Trail Trek is a fully supported, three-day, 109-mile point-to-point adventure — meaning every mile brings something new, with no repeats and no backtracking.

Each day delivers 30–40 miles of unforgettable riding, thoughtfully designed to balance challenge, scenery, and pure enjoyment. With just one curated route per day, riders can relax and focus on the experience while we take care of the details. Along the way, you’ll find well-stocked rest stops, friendly SAG support, and mechanical assistance whenever you need it.

To keep things simple and stress-free, limited transportation is provided at the beginning and end of the trek, making it easy to get where you need to go. All you have to do is show up, ride, and soak in three incredible days on one of the most iconic rail-trails in the country.

The registration fee includes:

• 2027 Annual Trail Pass 
• Shuttle service
• SAG support while on the route
• Portable restrooms at rest stops
• Snacks at specific rest stops
• Meals provided at Minkahata and Rochford rest stops  •Two Mickelson Trail Vouchers for Custer and/or Hill City and Deadwood.

The Black Hills in mid-September can bring a wide range of weather — and the trail’s changing elevations only add to the variety. Along the route, elevations range from about 3,400 feet at Edgemont up to nearly 6,350 feet near Dumont, meaning temperatures can shift quickly as you ride.

What to expect:

• Cool mornings & evenings: ~50–65°F
• Warm daytime temps: ~75–90°F
• Weather can be unpredictable: mid-afternoon rain showers or even hail are possible

Because conditions can change rapidly — especially with elevation gain and loss — it’s strongly recommended that riders plan to layer clothing so you can adjust throughout the day. Major swings in temperature can happen in just a few minutes, especially on long climbs and descents.

Clothing & Gear Tips

Layering is key:

• Start with a breathable base layer, add a light insulating layer for cool mornings, and have a wind/rain shell handy for afternoon weather changes.
• Ride prepared for ups and downs:
• You’ll sweat on climbs and cool off fast on descents — having a lightweight long sleeve or windbreaker makes a big difference.
• Warm gear for mornings & evenings:
• Lycra tights or leg warmers are great options for chilly starts and finishes.

Essentials for comfort & safety:

• Padded cycling shorts for long distances
• Cycling gloves to protect hands and improve comfort
• Full water bottles — hydration is critical
• Sunscreen and sunglasses

Hydration & Safety

It’s vital to drink fluids consistently throughout the ride to avoid dehydration, especially during warm daytime temperatures. Bring full water containers and refill whenever possible along the route.

And of course…

Mandatory Safety Gear

BE SURE TO REMEMBER YOUR HELMET!

Helmets are required for participation and are one of the best ways to keep you safe while enjoying the ride.
