It was a balmy morning for thousands of people participating in the Detroit Free Press/Talmer Bank Marathon.

Over 26,000 runners of all skill levels took part in the 40th annual event Sunday morning.

The winner was Jonathan Mott of Florida, who clocked an unofficial time of 2:22.53.

Part of the course included a trek across the Ambassador Bridge, down Riverside Drive and a return trip to Detroit through the Windsor-Detroit tunnel.

The tunnel was closed until 10 a.m. The Ambassador Bridge remained open, but lanes were restricted.

The event is a qualifier for the Boston Marathon.
