Hagg Mud 50K/25K, Gaston OR

The Hagg Mud 50K/25K is scheduled for February 13, 2027 and is organized by the Oregon Road Runners Club. The event takes place at Henry Hagg Lake in Scoggins Valley Park near Gaston, Oregon, with the start and finish at the C-Ramp recreation area.

The event offers the following distances:

  • 50K
  • 25K

Both races begin with a group start from the C-Ramp parking area, a short loop around the lot, and a brief single-track section. Runners pass through Sain Creek Pavilion and use Sain Creek Road for an out-and-back gravel section, which contains the largest elevation change on the courses. The 50K follows a counter-clockwise single-track loop around Hagg Lake twice, and the 25K follows the same loop once. Named aid stations on course include Dam and Fenders Blue, with the 25K aid stations located at roughly 7.3 and 12.5 miles.

Aid stations are cupless; participants must carry their own handhelds, cups, or hydration packs. Stations provide refill options including pitchers and rapid-fill spigots, and offer fruit, sweet and salty snacks, soda and GU products. The race includes waste reduction measures such as recycling and food waste buckets.

Registration includes aid stations, a post-race party with warm food and drinks, a parking voucher, covered bag drop, and warming/changing tents. Personalized bib deadline is February 2, and registration closes February 10 at 11:59 PM Pacific Time. The event does not offer refunds or transfers, though transfers from the 50K to the 25K may be allowed if spots are available.

Results and awards are separated by gender divisions for men, women, and nonbinary entrants, with top finishers in each division receiving prizes and all finishers receiving finisher socks. The event partners with the Trail Mix Fund to offer entry fee support for BIPOC and LGBTQIA+ participants and maintains a gender inclusion policy outlining eligibility and respectful conduct.
