Former New York Giants running back Tiki Barber kept his streak alive Sunday, finishing the Walt Disney World Marathon in 5 hours, 12 minutes.

It was his 13th marathon. The heat caused officials to issue a heat advisory and remind runners to stay hydrated.

His time was about an hour slower than his personal best, a 4:18:24 at the New York City Marathon in November.

Barber, 44, said he stopped along the way to take pictures with the Disney characters who were stationed along the route.

Barber said he weighs about 30 pounds fewer than he weighed while playing football.

He said the toll on his body during a marathon is different than in football.
