JOIN US OCTOBER 15, 2017 – Detroit, Michigan
The Detroit Free Press Talmer Bank Marathon is run every October in Detroit, Michigan, USA and Windsor, Ontario, Canada. The course is international and crosses the Ambassador Bridge and the Detroit-Windsor Tunnel between Detroit and Windsor. Due to its use of the tunnel, the race is able to boast that it has the only official underwater international mile in the world, as the tunnel runs underneath the Detroit River. The race is a USATF-certified, Boston-qualifier course.
