Fans, runners, friends and family of the MDI Marathon voted in the Marathon Madness Bracket Challenge and the MDI Marathon defeated the Akron Marathon in the 8-9 match up. Now, the MDI Marathon is ready to pull an upset of epic proportions by knocking off the #1 seed Chicago Marathon with YOUR help!

There's already been one #1 seed knocked out, the Baltimore Marathon a 16 seed knocked out the Baystate Marathon in the opening round 56%-44%, so there's no reason that the MDI Marathon can't prevail!
