The course and time requirements

The International Half-Marathon will showcase some of the best features that Detroit and Canada have to offer. The course will include trips across the Ambassador Bridge and through the Detroit-Windsor Tunnel, plus a route moving through Downtown and Midtown Detroit. Things wrap up at the foot of Campus Martius.

With a wave start, smaller groups of participants are sent off at three-minute intervals beginning at 7 a.m., which eases congestion in those early miles. Groups are based on the projected pace indicated on the registration form, so an accurate response is necessary.

A Last Chance Pacer will be provided for your event. The pacer will travel at the average pace needed to cross the finish line in four hours. Your progress will be monitored throughout the race. If you fall significantly behind the pacer, you will be given fair warning to pick up the pace. If you can’t keep pace, you will be required to board a bus following the pacers to be transported back to the start-finish area. We will close the International Half-Marathon course at 11:30 a.m.
