More than 4,000 runners are expected to hit the streets for the Detroit Free Press/TCF Bank Marathon this weekend to run for a special cause.

The race events, scheduled for Oct. 19-20, are aiming to generate $2.2 million for more than 45 charities, according to Executive Race Director Barbara Bennage.

A total of $1.15 million has been raised so far by charity partners, which link their fundraisers through the CrowdRise platform.

The marathon donates clothing and shoes left behind from the runners to the Fort Street Presbyterian Church’s open-door program, which feeds nearly 1,000 people each month and offers clothing, showers, medical and dental screenings and other forms of care, according to the church’s website. The drop-off area is located at the health and fitness expo, Bennage said. Leftover food and water is donated to the Forgotten Harvest in Oak Park.

Forgotten Harvest also had a team of four, who ran the marathon.
