Overview

Set your sights on a bucket-list trail experience as the historic Route of the Hiawatha trail opens exclusively for runners in the annual Hiawatha Fall Trail Run—a standout event hosted by Negative Split.

A Trail Transformed
Originally a scenic railway corridor, the course traverses 1.8-mile tunnels (including the iconic Taft Tunnel), majestic trestles, and stunning waterfalls before ending at East Portal. Marathoners, half marathoners, and 10K participants share the same awe-inspiring route, turning a familiar cycling path into an unforgettable run.

Course & Support
Beginning and finishing at Taft, MT, the half marathon kicks off at 9:30 AM PDT, with the marathon starting at 9:00 AM (and early-start option at 7:00 AM), followed by the 10K at 10:00 AM. Expect a 4.5-hour cutoff for half finishers (18:40 min/mile) and full support including cup-free aid stations, gear drop at mile 2 (Roland), and bike patrols across the tunnel-wilderness zones.

Why It’s Special
This one-off switch of a bike trail to a trail race brings unparalleled solitude—forest canopies, rushing falls, and echoing passages through century-old tunnels. Add to that the camaraderie of a trail-lovers’ crowd, commemorative shirts, medals, optional hoodies, and hearty post-run meals—social perks on an epic route.

Course Description

Run over scenic trestles, past waterfalls, and through some of the longest railroad tunnels open to foot traffic (1.8miles long). This will truly be a running experience of a lifetime!

All courses are out and backs.  This is primarily due to not being able to shuttle bus over St. Paul Pass.  There is also NO CELL PHONE SERVICE at the start, finish, or along the course.  The route is run on a railroad grade that is not steeper than 1.5% along the route.  Runners will get a good warm-up running the slight downhill grade before turning around to finish strong back up the gentle grade.  A 1.5% grade is the equivalent of 80ft of elevation change over a mile of the route.

Highlights: 1.6 mile long Taft Tunnel, 8 total tunnel sections, 6 trestles, waterfalls, scenic views, 5 aid stations

The Half Marathon will start out running through the famous Taft Tunnel for the first 1.6 miles. Runners will then exit the tunnel at Roland and hit their first aid station and a self service gear check near mile 2. As they continue past tunnel 21, runners will hit a second aid station near moss creek. After tunnel 24, runners will start to cross a series of trestles. After Trestle 220, runners will hit an aid station the half marathon turnaround running back along the trail the same way they came. After hitting the Roland aid station for the last time, runners will enter the Taft tunnel for the last 1.6 miles as they run toward the finish. The Half Marathon course will finish at East Portal.
