The highway, which runs between M-104 in Crockery Township and Lake Michigan Drive (M-45) in Robinson Township, will be closed to motor vehicles from 5 a.m. to 1 p.m.
The M-23.1k will begin at 8:30 a.m. at Robinson Elementary School, 11801 120th Ave.
The first M-231 run took place shortly before the official opening of the state highway a year ago. The run raised more than $9,000 for Ottawa County’s non-motorized pathway system.
Awards will be given out at the Post Race Party at the Pipeline Smokehouse & Bar, 9104 U.S. 31, West Olive. The party starts at 10:30 a.m. A buffet will be available for purchase.
The 14.3-mile (23.1 kilometers) race starts at the school and goes through the woods to the highway. There, runners go south to M-45, turn back north to M-104 and then return south to the school.
Registration for the race closed Tuesday. There is no registration on the day of the race, but you can still register at packet pickup this afternoon (Friday).
Spectators can watch the start and finish at the elementary school. There is also spectator access at Lincoln Street, M-104 and M-45.
Biking spectators are also allowed, but are asked to ride only between spectating sites and keep a close eye out for runners. Spectators are not allowed to bicycle along with a runner.
The distance from Lincoln Street to the Grand River is 2 miles. It is approximately 7 miles between M-104 and M-45.
