CAPE CORAL, Fla. - Sunday morning is the Mangrove Marathon in Cape Coral, the first-ever marathon organized in Lee County.  And Friday night, racers lined up to pick up  numbers, shirts and gear up for the big day.

Organizers say they already have well over 300 signed up for the race. A reason for the popularity - the course is flat, fast, and a certified Boston Marathon qualifier course. For those not running the entire 26.2 miles, there is also a half marathon, 2.62 mile mini marathon, kids race and relay.

"We are smaller than most marathons, but being our first year, we are
pretty excited about that," organizer Lindsey Ulrich said. "We definitely didn't expect that big of a number. We started out originally hoping we'd get 100, 150, so this
has definitely exceeded our expectations."

"I think it's going to be a lot of fun, and I hope it stays and becomes a tradition because we've got a lot of  good races and this will be a signature race hopefully," first-time marathoner Frank Vecchione said.
