About


The idea for an ultra version of the Mt. Baker Marathon was envisioned by Dan Probst in 2012. In 2013 a group run from Bellingham Bay to the summit of Mt. Baker and back was attempted. All three first attempts of the 108 mile route would end without a return trip; lightning storms, pouring rain and exhaustion delayed a successful summit and return. On the forth attempt in August of 2014 Beat Jegerlehner, Aaron Poh and Daniel Probst made the summit and return trip to Bellingham in 48 hours and 17 minutes. These group runs were repeated in 2015 and 2016 with 12 more runners adding their names to the list. 

Since day one the goal has been to test a route and logistics that would lead to a race. Finding a route that could be permitted proved to be a difficult endeavor. After exhausting all efforts to host the race from Bellingham, a new route had to be found. Two routes were officially used for the early races, the Deming route and Glacier route, and in 1912 a third route from the town of Concrete was thrown into the mix. The Concrete route would prove to be the winning (permitted) route for the modern day ultra version of the race. 

Herman Schrieber was the only contestant to use the Concrete route in 1912, pictured here on his horse in downtown Concrete. Herman's cabin once stood near the current location of the Schrieber's Meadow trailhead. Runners will pass by this location on their way to Sherman Peak.
