Pigtails Challenge
The Pigtails Challenge is a multi-distance ultrarunning event held at Lake Youngs Watershed near Renton, Washington. The course is a rolling loop that gains 900 feet of elevation each lap. The loop format concentrates climbing into repeated circuits so accumulated vertical gain can be substantial; for example, 100 mile participants complete ten loops, equal to 9,000 feet of vertical gain.
The event offers multiple distance options on the same course, including:
- 200 Mile
- 150 Mile
- 100 Mile
- 100K
- 50K
For the longest options, the initial portion of the 200 mile and 150 mile races is run independently and without event support; the final 100 miles of those entries are run together with the 100 mile field. The loop layout provides frequent pass points and centralized support opportunities for runners on the course. The setting is not described as technical mountain terrain, but repeated climbing and multiple laps create sustained physical and mental demands. The venue address is given as 16640 SE Old Petrovitsky Road in Renton, Washington. Visit the organization's website for the most recent information.
