This Event Took Place Sat. Feb 17, 2001


An Oregon classic ultra since 2001, the Hagg Mud Runs is a race you've got to try at least once. If you're looking for a mid-winter challenge, look no further than the ORRC Hagg Mud Runs - a 50k and 25k on the muddy, rolling trails around Hagg Lake, just outside of Portland. A fantastic event for the first time trail runner as well as the experienced trail vet, the Hagg Mud Runs offer an old school ultra experience with all of the perks of the newest races. Enjoy fully stocked aid stations, a well marked course, finishers swag, and hot lunch with celebratory beer when you finish. If you're looking for a little extra challenge, consider the Hagg Mud Double; run both races (one on Saturday, one on Sunday) and earn a growler full of your favorite beverage.

2022 Update

Celebrate our 20th anniversary with us!
That's right - this will be the 20th anniversary run of one of Oregon's original ultras. And while the trail is in better shape than ever, we will still offer one of the muddiest, gnarliest trail runs you're going to find this winter. Whether this will be your first Hagg Mud or your 15th, we promise to bring you a top notch event with well stocked aid stations, a hot meal and epic swag. We remain a non-profit race with any proceeds benefitting the Oregon Road Runner Club.

Sign up in the first seven days of open registration and save 20% to celebrate 20 years! After November 7th, registration will be $85 for the 25k, $120 for the 50k, $150 for the double and $135 for the "baby" double. Parking passes are included in this year's registration fees.

The Saturday 25k+ is once again an option for runners looking to do the "Baby" Double (25ks on both Saturday and Sunday, and yes, you will earn a growler - but it's going to be a "baby" growler - 32 oz) or who prefer to run on Saturday. The cutoffs are also very generous on Saturday, making this a fantastic option for runners who might not be sure about their pace. The 25k on Saturday will be a little longer than the 25k, as you will do the 50k out and back for a grand total of about 17 miles.

Hagg Mud Runs seeks to foster a trail running community that encourages understanding, appreciation and acceptance of all within its participants, volunteers and race officials. We believe that broad and diverse participation adds significant value to the trail running experience for all of us. We will be adding a non-binary gender category to our race this year. While we are unable to designate this option within Ultrasignup, we will be able to add your preferred gender to our results. There is a question on the signup page that will allow you to choose the non-binary gender designation; we will amend our final results to reflect your preferred gender category. Additional information on our efforts towards greater inclusion can be found on our website.

Hagg Mud went cupless in 2017! Hagg Mud no longer has cups at any aid station for liquids. Please plan on bringing your own cup for aid station refreshment. We feel this is a smart thing to do for the environment. We will also be continuing our recycling initiatives to our race in order to limit our environmental impact and to achieve as close to zero waste as possible.

Here are some important dates:

  • December 15th will be your last day to order a commemorative pottery cup, and January 1st will be your last day to order a long sleeve fleece zip jacket with the Hagg Mud logo for this years race. Race shirts are no longer included with your registration and must be purchased separately.
  • January 15th is the last day to sign up for a double in order to have a guaranteed growler of your choice. Your growler request will be due February 1st.
  • Online race registration closes on Friday, February 11th. There will be day of race registration however. There is no cap to the number of runners who can run either Saturday or Sunday. Tell your friends and family to sign up!

    Training Run Opportunities
    January 8, 9:00am - Hagg Lake
    What a better way to prepare for race day than to run around Hagg Lake! We meet at the large parking lot on the far side of the dam.

    January 22nd, Hagg Lake, Trail Work Party 9:00am
    Everyone who attends gets free parking at the lake. We will work to ensure the trail is ready for race day on our trail work day. We meet at the large parking lot on the other side of the dam. This is a great way to earn four hours of trail work early in the season. Please let us know if you have any questions.

    General Information

    IMPORTANT: Hagg Mud does not provide refunds should you be unable to run on race day.We also do not accept transfers. There are no exceptions to this policy. Please know that your race fee is going to a non profit that helps further the sport of running in our community.

    Hagg Mud is a running event; it is not a walking event. We understand that walkers would like to participate but we need to keep in mind our volunteers that are working race day, so we must enforce cutoffs that require an average pace of 17:10 per mile. You will be pulled from the course if you do not make the stated cutoff times. The Saturday 25k+ has a generous time limit and is better suited to those who wish to hike. You will have 9 hours to complete the 17 miles, which is an average pace of 31:00 minute miles. This is a great event for first timers who are unsure of their pace!

    50K Start Time - 7:00am, Saturday, Feb 19, 2022
    25K+ Start Time - 7:00am, Saturday, Feb 19, 2022
    Cutoff for the first lap is 12:00pm. Any runner not through the start/finish line for their second lap will be unable to continue. You must be through the dam aid station by 1:15 pm and through the Fenders Blue aid station by 3:00 pm. This is a 17:10 minute average pace per mile.

    Runners in the Saturday 25k+ (remember - you are doing the first loop with the 50kers, so the out & back is longer!) will start at the same time as the 50k runners. You do not have a cutoff time for the finish; if you finish after 12:00pm you will still be considered an official finisher.

    25k Start Time - 9:00am, Sunday, Feb 20, 2022
    Because of permit requirements, the 25k course will be run in the same direction as the 50k.

    Late Registrations

    Please note if you register AFTER Friday February 11th, you can only pick up your bib at the event. Your bib will not be at either of the early packet pickups.

    50K Course

    The 50K consists of a group start at Boat Ramp C parking area. We will be adding the loop around the Boat Ramp C parking lot at the start in order to spread out runners before hitting the trail. Runners enjoy a little over 3 miles of an out-and-back on a gravel road. This really helps runners to spread everyone out along the course. Please note that this is the biggest elevation change you will encounter for the entire race. When runners come back through the Sain Creek Pavilion, they'll have a chance to shed clothing and prepare for the trails. This is when the mud starts. You will run around Hagg Lake counter clockwise 2 times on the single track trail, pass by a 5 aid stations including the start finish, and eventually make your way back for the post race festivities.

    25k+ Course

    The Saturday 25k+ course consists of the first loop of the 50k race. You will do the full out & back with the 50k runners, which means your 25k race will actually be about 17 miles. You will do one full counterclockwise loop of the lake before finishing back at Boat Ramp C.

    25K Course

    The 25K consists of a group start at Boat Ramp C parking area running through the parking lot that helps spread out the runners. Runners will then go through the Sain Creek Pavilion and parking lot up Sain Creek Rd. Runners enjoy a little less than 1.5 miles of an out-and-back on a gravel road. Please note that this is the biggest elevation change you will encounter for the entire race. Runners will then come back through Sain Creek Pavillon to hit the trail. This is when the mud starts. You will run around Hagg Lake counter clockwise 1 time on the single track trail, pass by a 2 aid stations and eventually make your way back for the post race festivities.

    Optional Swag Purchase

    We have two options for this year's merchandise purchase. One is a black full zip fleece with the Hagg Mud logo. The other option is a commemorative pottery cup with the Hagg Mud logo. Orders must be placed by December 15th to guarantee a cup and January 1st to guarantee a jacket. Limited stock will be available for purchase at the race.
