5K Trail Run – Sunday, August 27, 2017


The Underdown Trail Races are new, grassroots trail runs in Northern Wisconsin. It’s conveniently located only 6 miles off of Highway 51 and offers runners a wilderness experience on challenging trails. We look forward to seeing you this summer.


  • This is a challenging trail run on challenging terrain that goes through some remote areas.
  • Cell phone service will be spotty at best.

  • It is meant to be a physical and mental test that allows you to test your trail running mettle.

  • Finish it and you just might burst with pride and happiness!

5K Course:


  • Elevation Gain: We will get the exact information when we can get out later this spring. You can expect about 50-100 feet per mile. This terrain is very much glacial, up and down, and not easy. Expect a wilderness type experience on tough terrain.
  • Surface/Surroundings: Mostly forest singletrack with a few gravel road crossings. The ground there is a result of glacial deposits. You can expect rocks, roots, dry to loamy dirt and everything in between. You’re traversing all the ups and downs that the glaciers left behind. In sections you’ll be on hillsides and then you’ll drop down into areas that have marshes near the trail. You’ll see lakes, ponds, and A LOT of trees.
  • Aid Stations: We are working on exact aid stations, but you can expect at least one aid station on the 5K course. Our aid station is manned by volunteers, many of them spending a good part of their weekend out there – please be sure to thank the volunteers!  The 5K will have water
  • Pacers & Crew: Pacers are not allowed. Any runner found running with a pacer who is not a registered runner (“a bandit”) will be disqualified.  Your crew members may offer support but at the aid station locations only, no other spot on the course is acceptable.
  • Info For Crews, Spectators and Family (runners please share this with your crews): It is critical that every runner’s crew or a spectator drives slowly and stays away from other runners near the aid stations.  Vehicles near or at an aid stations can ruin the day for everyone.
  • Headphones: We do not recommend the use of headphones. However, we won’t tell you can’t wear them. Full awareness of one’s surroundings, and the ability to communicate with other participants, race volunteers, and trail users not associated with the event are critical to everyone’s safety.
  • Littering: Please don’t litter. If you are caught in the act of littering on course, you will be asked to leave and not invited back. If you see some trash someone else has dropped, please pick it up.  There will be garbage bags at the aid stations.
  • If You DNF: If you have to quit the race, please call or text 608-385-2706 with your name and number or alert the nearest aid station and they will alert that number. You are responsible to get yourself off course and back to home base. If you leave the course and fail to notify race officials, you are not welcome back to our races.

It’s important that you use common sense, follow the rules, and be nice to ensure everyone’s enjoyment, safety, and overall experience. If you break the rules or do any other shenanigans, we have the final decision in dq’ing you. If you see someone being “one of those people,” you can find someone involved with the race and we will handle. Thanks for being nice.

  • NO LITTERING. This applies to on course, in the parking lot, and everywhere. Please pick up any garbage you see, no matter how small it is.

  • Racers cannot stash support including nutrition, equipment, or any other gear or items on course prior to the race. We are providing an aid station and 50k and 50 milers will get to have a 2 gallon drop bag. Half marathoners do not have drop bags.
  • Headphones are allowed but we discourage the use of them. We won’t tell you not to wear them, but your full awareness of your surroundings and your ability to communicate with everyone is important for everyone’s safety.
  • Strollers, dogs, bikes, and other non-running items are not allowed.
  • Racers cannot receive outside support on course during the race, except at designated aid stations.
  • Racers must let faster runners pass when it’s safe for them to do so.
