Baker Lake 50K

Baker Lake 50K is a trail ultra in Whatcom County, Washington, held on October 3, 2026, by NW Endurance Events. The single race is a 50K (31 miles) that starts at 8:00 AM, run in the Baker Lake area of the North Cascades.

Fifty kilometers is the classic first-ultra distance, and a lakeside forest trail is a welcoming place to take it on. Plan on roots, rocks and rolling terrain rather than long mountain climbs, which means the challenge is mostly about keeping a steady, sustainable effort for five to eight hours. If you have finished a trail marathon or a road marathon and run trails regularly, a 16-week build with a long run peaking around 22 to 26 miles, plus a few back-to-back weekend runs, will get you to the line ready. Practice eating every 30 to 45 minutes during your long runs and carry a small pack, since early October in the Pacific Northwest can turn wet and cool. Experienced ultrarunners can treat the distance as a fast late-season effort.
