Thousands of runners are set to roll through streets on both sides of the border for the 41st Detroit Free Press Marathon this weekend.

An estimated 20,000 people will participate in full and half marathons Sunday. Road closures will begin on both sides of the river at 6:45am and will be lifted at 10am.

Runners will travel over the Ambassador Bridge into Canada, then north along Huron Church Road to Riverside Drive before continuing east to Goyeau Street then south to the Detroit-Windsor Tunnel.

The Ambassador Bridge will remain open for the run while the tunnel will be closed for the duration of the race.

Transit Windsor has added additional buses from the Windsor International Transit Terminal beginning at 5:00am until 5:45am, with return trips from the Mariners' Church terminal in Detroit running from 11am until 2pm.

Those taking the tunnel bus across for the Lions game will be dropped off at the Mariners' Church due to the race. Fans will be picked up from the regular stop on Gratiot Avenue following the NFL matchup between Detroit and the Minnesota Vikings.
