Lace up for an unforgettable trail running experience at the Wicked Worm, set to challenge runners on June 20, 2026, in scenic Grand Rapids, Michigan. Hosted at the picturesque Robinette's Apple Haus, this event offers a unique blend of endurance challenges with distances including a 12-hour, 6-hour, and a 10K. Prepare to navigate what is renowned as one of the most technical trail systems in West Michigan, featuring a demanding course with plenty of hills and a mix of technical singletrack weaving through beautiful orchard scenery.

The 12-hour and 6-hour races are contested on a challenging 4.2-mile loop course that encompasses sections of the West Michigan Trail Runners (WMTR) course around the orchard, while the 10K covers the entire WMTR course on the north side of the orchard. Runners can expect well-supported aid stations, including a main hub at the start/finish stocked with an array of snacks, quesadillas, water, and Tailwind, plus an additional water station along the timed loop course. Historically, race day conditions in late June typically bring highs around 80F and lows of 57F, with a 16% chance of precipitation, so runners should be prepared for warm temperatures and potential humidity, especially during sections outside the shaded woods.

The Wicked Worm is more than just a race; it's a community event with a vibrant atmosphere. Participants in the 12-hour race can utilize pacers from 4 PM, and a welcoming environment allows runners to set up personal aid with chairs, canopies, and coolers along the course. After conquering the trails, all 10K and 12-hour finishers are treated to a delicious pancake and bacon breakfast. This event, organized by the West Michigan Whiskey Rollers, has established itself as a staple on the local ultra-running calendar, celebrated for its challenging yet rewarding course and excellent organization.
