Thousands of runners toed the line Saturday, tackling the ups and downs of the Bix 7 road race.
It is a tradition for area families and world class athletes every year.
More than 20,000 runners and walkers challenged themselves on the course this year.
Many of these people were running or walking for the first time, while others tell us they haven't missed a year.
"This is an awesome race to run," Danielle Cooney of Deergrove, Illinois, told us, "I mean, I ran a half marathon and a full marathon and the Bix is my favorite."
The unseasonably cool weather may have helped out many of the runners this year, but the course was as challenging as ever.
But, it's not just the elite runners who are coming out on top this weekend. Local businesses are also getting a nice boost from the big crowds.
Past Bix weekends have brought about two or three million dollars into the Quad Cities. The handful of area businesses we talked to Saturday said they've been too busy to stop and count how many guests they've had or how much money they've spent - and the Quad Cities Convention and Visitors Bureau says it doesn't have a count yet either - but everyone says it was a lot.
The Barrel House in Davenport said it had at least a few thousand coming through Saturday alone. The staffers we talked to there say it was much busier this year than it was last year.
And, retail stores and other restaurants we talked to say they probably didn't fare as well as some area bars and pubs, but business was still better than usual.
Many of the hotels we checked in with also said they were seeing a lot of visitors - but they weren't completely booked from the Bix.
Convention and Visitors Bureau Officials say that makes sense:
"One of the trends we've had over the years is we've built a lot more hotels. There are a lot more hotel rooms than there were 10, 15, 20 years ago," Joe Taylor, President and CEO of the Quad Cities Convention and Visitors Bureau, explained.
"At one point we were filling hotel room from Galesburg to Iowa City," he added.
The Convention and Visitors Bureau also says it expects many of this weekend's visitors to return, or to tell others about the Quad Cities, and that's expected to boost tourism here in general.
The Convention and Visitors Bureau estimates each overnight visitor here for the Bix spent about 180 dollars in the Quad Cities this weekend.
