FORT WORTH Tanner Leggett is about to become an ultra-marathoner. The 31-year-old will run 31 miles Sunday in what's becoming the CowtownMarathon's biggest year yet.

HeidiSwartz, executive director, estimates seeing 80,000 runners and onlookers combined.

They're seeing huge numbers in part because the Dallas Marathon was canceled because of an ice storm, leaving runners like Margaret Kamau looking for a new race.

'We prepared for the Dallas Marathon but we didn't do that,' she says.

Runners are hoping for good conditions and a good course. Earlier this week, things weren't looking so good. At the intersection of Colonial Parkway and Country Club Circle,the road was ripped up and there were numerous gaping holes in the ground. As of Friday, city crews did as promised and cleared everything up to make sure it's safe for runners

'I knew they would, the city does such a great job helping us,' Swartz says.

But drivers beware. Anyone near the races Saturday or Sunday morning will likely face delays. The Fort Worth Police Department says drivers should expect delays on University and Montgomery north of Interstate 30 from 7 a.m. to 10 a.m.
