Thru the Leaves Half Marathon, 10K, & 5K offers the perfect challenge for trail running enthusiasts looking to enjoy a challenging run among southeastern Michigan’s gorgeous autumn scenery. Ready to get down and dirty?
Held in Rochester Hills’s Bloomer Park, the half marathon course involves two 6.6-mile loops on predominantly single track dirt mountain bike trails. Beware of roots and rocks on this often technical course, and prepare yourself for hills—the half marathon involves 900 feet of elevation gain!
From the starting line, runners travel through the parking lot to the trail, where they’ll start off strong by tackling 2.75 miles of single track (and 95 stairs)! The second half of the loop provides some relief, as the course flattens out, alternating between single and wide track. The last half mile of the loop takes runners around the finish line to start again.
On the course, water is available at the aid station at the top of the stairs. Water, Gatorade, and orange slices are also provided near the start of the second loop for half marathoners. However, if runners want more water throughout the course, they are encouraged to carry their own water bottles.
Feeling even crazier? Race organizers also offer a 6-hour two- or three-person relay option, to be held on Sunday, October 2. Gather a couple friends to tackle the course as a team, or—if you want to get truly wild—run the Saturday and Sunday races back-to-back.
Take Note
There is a $5 fee per car to enter Bloomer Park.
