DETROIT (WXYZ) — A Michigan man is running his first marathon on Sunday, the Detroit Free Press/TCF Bank Marathon, after losing 475 pounds.

Carlos Orosco has lost the weight since June 2016 with the help of bariatric surgery, but he has been able to keep the weight off by running and keeping healthy.

He also said he has a great support group around him to hold him accountable.

Good luck, Carlos!
