Race Structure
The Su Dog 300 is a non-profit organization focused on hosting a 300 mile qualifying race that is competitive while promoting education and fun!
To promote teamwork, mentorship, and general fun on the trails, there is no cash prize for top placing finishes in this race. In lieu of cash prices, we have prepared an assortment of amazing gift packages for every finishing musher. From chainsaws to sled bags to those new AK Gear bunny boots to Apocalypse mittens and beyond, we’ve got some great prizes lined up! Mushers will choose their prize at the Closing Ceremonies in order of their finishing place.
The Su Dog 300 is an Iditarod qualifier.
race route
The 2027 Su Dog will start and finish in Willow, making a large loop connecting the many communities of the valley including Willow, Caswell, Talkeetna, Chase, Trapper Creek, and Petersville.
Each leg of the race will be 45 - 100 miles with 4 checkpoints to be announced this Fall.
Our checkpoints are major sponsors of this race and we couldn't do it without them. Let them know you appreciate them by supporting their business.
Race Rules
Sections of the race rules that differ from other races in Alaska are in bold in the document above. Please read the rules and take special note to read these bolded sections to be familiar with Su Dog rules. Special rules of note:
Handlers are NOT allowed to assist their mushers aside from parking teams, delivering drop bags, and watching parked teams while a musher sleeps. Even if the musher is not using the race as a qualifier. We encourage mushers to enjoy the work and connection to their team during their checkpoint routine. Please see ruleset for specifics.
Every team needs it’s own handler. Due to the short distance between some checkpoints, handlers should not handler for more than one team.
Road crossings will be staffed by Su Dog, handlers are requested to NOT meet mushers at road crossings in order to reduce roadside hazards.
Lighted collars on lead dogs and reflective material on back of musher’s outerwear, harnesses, dog coats, and sled are required. The Susitna valley has high levels of snowmachine traffic; lighted collars and reflective fabric on dogs, sled, and musher are to promote the safety of all our participants.
The Su Dog 300 is proud to say we’ve partnered with Willow Dog Musher’s Association to provide FREE lighted collars for every team (to keep forever)!
Stay safe out there :)

how do i sign up?
The 2026 Su Dog sold out in under 4 minutes, so to promote inclusivity in our community we’ve decided to have a lottery process for the 2027 Su Dog 300.
Mushers who sign up in the 24 hour period between 12pm noon (AKST) on Oct 15, 2026 and 12pm noon (AKST) on Oct 16th, 2026 will be entered in the lottery.
At 6pm on Oct 16th, we will have a livestream on Facebook where entries will be drawn for the race. We will accept 20 mushers in the race and the remaining entries will be randomly drawn for their order on the waitlist.
Should I even bother with the waitlist if I don’t make it?
YES!!! Last year the Su Dog went through it’s entire waitlist (more than once)! That means every single waitlister was offered a spot in the race. If you want to run the race you absolutely should get on the waitlist!
starting 12pm on oct 15th, the sign up link will be here
After signing up you will be asked to email a signed copy of the waiver as well as a photo of yourself to sudog300@gmail.com
Here is the link to the waiver!
Using Su Dog 300 as a qualifier?
Here’s a link to the Iditarod Qualifier Form. You will be required to bring a PHYSICAL COPY of this form to the Musher Meeting so race judges can assess you during the race.
