Thanks to our friends at Linn County Trails Association for putting this resource together!

Heavy trail use on Sunday
The Cedar Rapids Marathon is being held this Sunday, June 7th. Please be aware that the marathon route will be using several parts of the trail on Sunday beginning at 7:00 AM and going until 1:00 PM. The marathon will be using the trail around Cedar Lake and will be using the Iowa River/Cedar Valley Nature Trail from Czech Village out to Highway 30. This is a large race with thousands of participants. While the trail is not closed you may want to use the Grant Wood Trail, Sac and Fox Trail, or CeMar Trail. You can also head north of Cedar Lake and start at the Boyson Road trailhead of the CRT/CVNT or head south of Highway 30. You can find maps of all the trails in the area at: https://www.linncountytrails.org/all-trails or stop by our booth at the Farmer's Market on Saturday to pick up a paper map.

You can see all of the CR Marathon race routes on the https://cedarrapidsmarathon.com. We've included an image of the marathon (all other races share parts of the marathon).

Numerous roads will also be closed for the marathon. These closures can be found at: https://cedar-rapids.org/news_detail_T6_R949.php

Despite news images circulating, Corridor Running (NewBo Half and 10K) is not affiliated with the Cedar Rapids Marathon weekend events.

Be safe, everyone who is participating!
