Registration opens for Twin Cities Marathon

Registration for the Medtronic Twin Cities Marathon and six additional running events hosted by Twin Cities In Motion will open at 10 a.m. Tuesday.

The Twin Cities Marathon, which runs from downtown Minneapolis to the State Capitol grounds in St. Paul, will be limited to 11,600 participants and held Oct. 9.

Twin Cities In Motion will also open registration for three other events the weekend of the marathon: the TC Family Events, TC 5K and TC 10K, which are Oct. 8. Registration for the TC 10 Mile, which is run the same day as the marathon, will open July 6.

The date for this year's marathon weekend is a week later than usual, because of the Ryder Cup being held at Hazeltine National Golf Club in Chaska the first weekend in October.
