Detroit is gearing up for a busy day with the Free Press marathon trade show and a Trump campaign rally

(CBS DETROIT) – The annual kickoff event for the Detroit Free Press Marathon competes against a political rally for former President Donald Trumpwhich could cause traffic problems for commuters on Friday.

“You will not have to go through any safety protocols to access and navigate our expo,” Aaron Velthoven, the marathon’s vice president and race director, said Thursday.

However, Velthoven said the marathon was only warned 48 hours before the rally began at Huntington Place because the health fair and expo was coming to an end. He told CBS News Detroit that they could rotate and relocate within the convention center.

“Everything should go smoothly,” said Velthoven. “But they may want to allow a few extra minutes to get around, just in case.”

The marathon brought in over $28 million for the city of Detroit last year and is expected to break records, including the race record of selling out two months before the start. Organizers said there are over 26,000 racers this year, with all 50 states represented and over 40 international participants taking part.

“Our primary mission is to patrol and keep everyone in the community safe,” Detroit Deputy Chief Arnold Williams said when asked about the collision of the two events. “We are able to control and secure the visits that take place.”

The exact route of the former president’s motorcade has not been announced, but commuters should expect heavy traffic in downtown Detroit during Friday’s rush hour.

As the weekend begins, you can expect there to be road closures on Saturday afternoon that will continue until the last runner crosses the finish line on Sunday.
