IN-PERSON & VIRTUAL EVENTS
The in-person event is scheduled for April 12, 2025. There is also a separate registration page for a virtual option in 2025: Check the linked Endless Trails events for that registration page.
Race registration fee notice
Please note: While the registration button displays the all-in price, including fees, you'll see these fees removed during checkout. Our race director has generously opted to cover all processing fees for participants.
2025 COVID PRECAUTIONS
For the 2025 in-person event, we'll have a number of Covid precautions in place, including social distancing in communal areas (such as at check-in and the aid station). If these precautions are too much for you, we ask that you stick to the virtual event (available on a separate registration page). Thank you for your part in helping protect our respective communities!
A REVERSE TAKE ON OUR CARKEEK 12-HOUR: TOUGH & FESTIVE!
2025's 11th! annual event will include both an in-person option (April 12th) as well as a virtual event running from April 1st to April 30th on a separate registration page [In which case you can hop to it on your local trails, with a bonus prize for whoever can best simulate a course like Cottontail!].
With gorgeous views of the Sound, varied terrain (rolling trails, steep stairs, a section or two that might generously be called “flat”), and a festive atmosphere, we think this is a race you (and your family, and friends, and well-behaved, leashed dogs) will just keep coming back to—one 1.93-mile lap at a time. Run for twelve hours, run for six. Run as few or as many hours as you like! Every single runner will get something awesome simply for showing up to run, but this isn't your typical medal-laden sort of endeavor. (We hand-make our bibs, count your laps with star stickers, and the first time we directed this race, winners won giant stuffed dragons. Winners have won a variety of things over the years, including bright pink and/or green garden gnomes.)
In addition to being heaps of F-U-N, our races are also low-impact: You won’t find any paper products at the Cottontail 6- & 12-Hour, and we strive to have less than one full bag of trash at day's end. We also avidly support local businesses, which means as much aid (and prizes!) as possible will come from local businesses. Speaking of aid, we'll have some of the best out there. We'll bring you awesome fuel as your legs run loop after epic loop, and we'll have great, locally-sourced prizes to raffle off throughout the day, too.
GO GO GADGET EPIC LOOPS
This isn't your average loop race. Cottontail is run on a clockwise, 1.93-mile loop in Seattle's gorgeous and rugged Carkeek Park, with an additional .54-mile loop open most of the day to give you more distance options and keep things fresh. You're welcome to run as few or as many loops as you'd like during your 6- or 12-hour stay with us, but here's what to expect on each loop: steep stairs, rolling trails, gorgeous vistas, loads of singletrack, green trees, glorious ferns, spring flowers, lots of up and lots of down. These loops might be short, but they're never going to feel that way. Each loop contains 436' of vertical gain, which adds up QUICKLY, so expect to (have fun, yes!, and) be challenged.
We promise at the end of your day you'll feel proud of yourself, no matter how many miles you run. (We promise we'll be proud of you, too.)
AN AFFORDABLE FUNDRAISER FOR NORTHWEST TRAILS
We pride ourselves on keeping these races affordable. Prices start at $50 for the 6-Hour and $60 for the 12-Hour, including all taxes and fees. And nearly all of your registration goes back to trail work and advocacy! Additionally, for the virtual event, the 6-Hour AND 12-Hour starts at a friendly $35 (including applicable sales tax & UltraSignup processing fees), with zero price increases.
This race, like Carkeek in the fall, is an Endless Trails fundraiser, so any and all funds that don't go to race-related costs (including awesome aid and prizes) will go to our 501(c)3 nonprofit to support trail work, trail education, and trail advocacy throughout the Northwest region. We'll be accepting cash and check donations on the day of the event, too, and you'll also have the option to make an additional tax-deductible donation to Endless Trails as you're registering. Every little bit helps, and all of it goes back to good and much-needed work on local and beloved Northwest trails. Thanks for your support! #RunningForTrails
