The Experience

The Girdwood Marathon is a true test of endurance, set amidst the stunning temperate rainforests of Girdwood, Alaska. This event isn't for the faint of heart, with its course weaving through over 30 named trails, including the infamous Winner Creek Trail and sections of the Iditarod Trails. Runners can expect a rugged experience, potentially involving soggy ground and glacial creek crossings, making it feel more like an ultra than a traditional marathon.

First conceived by Brian Burnett, who envisioned sharing the joy of Girdwood's extensive trail network, the marathon has become a unique challenge. With a typical field size of around 203 finishers and runners coming from about 10 states, it offers an intimate yet demanding race day. The event, first run in 2025, is held annually on October 3rd, with the full marathon starting at 9:00 AM and the half marathon at 10:00 AM, promising fewer cold toes for the latter.

Race-provided description

Giddy up!    This trail marathon covers some of the amazing trails in Girdwood, Alaska. Our town is known for over 30 plus meandering trails through the beautiful temperate rain forest. This is NOT the race to run if it's your first marathon. "This marathon feels like an ultra run" says marathon finishers, so perhaps volunteer to sweep race course, or work at an Aid Station your first year. Volunteers are guaranteed a spot the following year! OR...sign up for the 5K Family-Friendly Race and then volunteer and cheer on the finishers! This run includes the infamous Winner Creek Trail, the Upper, Middle, and Lower Iditarod Trails, Nordic 5K Loop, Tiny Trail, Athabascan Trail, California Creek Trail, Abe's Trail, Beaver Pond Trail, Bird-to-Gird Trail, Winner Creek Extension Trail, Alyeska Bike Path, and various Alyeska Resort mountain trails including the NEW Kettle Pond Trail. This Marathon is the brain-child of Brian Burnett who is constantly connecting trails for a fun day outside.  He ran a solid 26 miles one day and thought, "More people should experience this fun...we should have a trails marathon". So if you love soggy October runs through Alaskan forests and perhaps losing the feeling in your toes running through glacial creeks...come join us on OCTOBER 3rd, 9:00AM for Full Marathon, and 10:00AM for Half Marathon (fewer cold toes).  If you have someone coming to watch, or if you both want to check out the course and have unlimited access to Aid Station Gummy Bears - then volunteer your first year...or "volun-tell" your cheerleader to help out.  (leave dogs at home)  Seriously - even spectators - leave dogs at home.   AID STATIONS:  1) Alyeska Daylodge, 2) Nordic 5K Loop / Winner Creek Trail connection, 3) Middle Iditarod Trail at USFS parking lot,  4) Crow Creek Rd at California Creek Trailhead, and 5) Bird-to-Gird Path Trailhead. Choose the full 26.2 (ish) mile marathon or 13.1 (ish) mile half-marathon, or - the 5K Race. The races start and end at the Alyeska Daylodge in Girdwood.  Aid stations? Yes, we will have FIVE stations stocked with snacks and water! WE have listened...more water. Got it. But we will have pitchers to fill YOUR hydration packs or bottles. Carry your water!! This is also a BYOBS race (Bring Your Own Bear Spray), so along with your OWN hydration and a smile, be prepared for wildlife encounters.  We will start the race with ONE WAVE PER RACE from the Alyeska Daylodge.  Parking is available, as well as bathrooms, and a place to store warm gear.  THERE ARE NO REFUNDS OFFERED. (Yes, even if the race is cancelled due to weather) THERE ARE NO BIB TRANSFERS.  PLEASE leave your dogs at home. You can tell them about the race later. Thanks. AGAIN THIS YEAR!  There will be a time cut off for the Marathon. Marathon ONLY - not half marathon. The marathon cutoff time will be 4.5 hours at the Crow Creek Rd Aid Station. This cut off time will be in place for the safety of runners and sanity of volunteers who help create a fun day for all participants. Really, it's safety.  These are wet trails in October and we encourage you to budget time navigating a few areas.  If you are interested in walking the course, then sign up as a volunteer course sweep instead of racing.  AIRPODS are discouraged so you can stay alert to wildlife and other runners. PLEASE LEAVE YOUR DOGS AT HOME. This applies to racers AND spectators since they tend to stand & cheer close to the finish line and food tables.  Race Day schedule and updated maps will be emailed to all Race Participants and Wait List Participants.  If you are on the Wait List, you have a 51% chance of running, so keep that Saturday open.  We will notify you as space opens. We will decide if Marathon Racers are running across Glacier Creek 5 days prior to the race.  If the water level is too dangerous, we will choose Plan B. After the race will be yummy Bake Shop sweet rolls, cookies, and Coast pizza to reward your efforts and keep you around for the awards!! This is a fundraiser for the Girdwood Nordic Ski Club. We use the funds to maintain the snow machines for winter grooming, maintain trails, and create trail signage.  We will also dedicate funds to help maintain trails on this marathon course.  We do not offer refunds unless you have a really really good reason like being deployed, or volunteering instead of racing. EVEN DUE TO WEATHER. We appreciate all of you coming to play outside in Girdwood and sharing our love for the Girdwood trail system.  We will have three categories for each race: Men's Division, Women's Division, and Non-Binary Division. See you soon!
