Race Information

Robinette’s Apple Haus & Winery, Grand Rapids, MI
9 am

Pick from two very fun and challenging trails. No need to decide until right at the start. Expect to run a lot slower than your normal road 5K time. You’ll suffer (a bit) and you’ll love it. The trails are test run and shortened or lengthened until they both take the same amount of time to complete.

Short & Brutal. 3.1 miles approximately. Large sections of off-trail running define this trail along with its unique obstacles. It’s a roller coaster like its sister trail but instead of constant small ups and downs, it features fewer but much more severe climbs and descents – including some tough sand dunes and the Wicked West Ridge. Make it through Provin Trails in one piece (1.5 mile mark) and then take on the roller coaster hills of Robinette’s north woods trails. From there, it’s a wild grande finale as you must make your way through the cornfield maze. Bushwhack through the corn or make use of the maze’s easier but longer trails. Your choice.

Long & Difficult. 3.4-3.5 miles approximately. Starts with a nice warm-up through the south orchard before crossing over 4-Mile Road to tackle Robinette’s north woods. Lots of ups, downs and turns, rooty at times, considered the most difficult trail in West Michigan mile for mile but totally doable. Join the Short and Brutal racers with a fun dash through the corn, using the corn maze trails or bushwhacking through them. You pick!

Robinette’s has parking both south and north of 4 Mile Rd. Please first try to park in the gravel lot on the south side, next to the gift barn. Parking Map.

Pick up your race number. Attach your number on the front of your front side, outer layer. Please don’t cover it up or the chip timing may not work. Come with your race number to help keep lines short. We’ll provide your race number via email the day or two before the race.

Portajohns are located at the start/finish only, between the Apple Haus and Gift Barn (see parking map). Please do not use Robinette’s bathroom due to septic limitations.

If you cannot attend the race, you must pick up your shirt at check-in, BEFORE the start of the race. We have no way of knowing who will or will not be at the race so we reserve the right to give away or sell all shirts once same-day check-in ends.

Weather, COVID
Race organizers reserve the right to cancel the event in the case of COVID conditions or extended severe weather. We will do everything possible to get the event in, but refunds are not available if it is cancelled due to significant costs we must pay in advance of the race.

Each race course will have one aid station with water and Gatorade.

Arrow signs (and possibly sprinkler-type flags) will be used to mark the course. Keep flags on your right. Be aware that sometimes the course may veer off the main trail. It’s your responsibility to follow course markings or your time and place will not count.

Ear buds/music is not allowed due to safety issues of not hearing sheriff offices at road crossings, volunteers, or runners who want to pass. Dogs are not allowed (except with spectators, leashed).

Enjoy a Robinette’s legendary donut (or two) and cider after the race and celebrate the top finishers and all finishers! We may also have enough prizes for a raffle of all registered racers.

Our charity partner for the Dirty Duel is Camp Anew, a branch of Starlight Ministries, that provides support specifically to children and teens ages 7-17; it is a place where campers will experience the value of gathering with other children who have experienced grief. Campers share their stories, capture memories, discuss their feelings, and have fun! Camp Anew is a biblically based Grief Camp operated at Warner Memorial Camp.

Thanks to Robinette’s for hosting and to Kent County Parks for the use of Provin Trails and the Kent County Parks Foundation for helping expand and enhance our park and trails system.
