The Chuckanut 50K course

A long-running Pacific Northwest 50K with a memorable lollipop shape: flat Interurban Trail out from Fairhaven Park, a hard technical 30K middle loop that climbs, traverses, and descends Chuckanut Ridge for about 5,000 feet of gain, then the same flat trail back. The closing stretch is faster than it feels, because your legs arrive at it having just been taken apart on the ridge.

Weather on race day

Mid-March near Bellingham is cool and usually wet. Expect temperatures in the 40s, mud on the ridge, and roots and rock that stay slick all day. Dry years happen and are not the way to plan.

What to train for

Technical descending and running well on tired legs. The final flat 5K decides finishing times, so long runs that end with steady running after a hard hilly middle are the specific preparation. Get comfortable on wet rock: this course does not reward tentative footwork.

Do I need an account to get a Chuckanut 50K training plan?

For this one, yes. The instant browser builder stops at the marathon, so an ultra plan comes from the coach itself, which needs a free account. Still no card, and the plan adapts as you log the training.
