Runners took their marks Friday night to help raise money for a Boston Marathon bombing victim with local ties.
Former Lady Vols swimmer Nicole Gross and her family were hurt in last month's bombing. Gross broke her leg, among other injuries, and her husband, Michael, who also swam at Tennessee, suffered head and arm injuries and had third-degree burns.
All proceeds from Friday's REV3 Glow 5K will go to Gross and her family.
About 1,500 runners raced through World's Fair Park.
Organizers say they hope the money raised will help the family.
"I do know that their reaction was one of immediate tears. So I know that they're appreciative of it, and you know, I just hope they know we really want to help out and hope it does help them," said Charlie Patten, the owner of REV3.
The entry fee for the race was $40, which means tens of thousand of dollars will be going to Gross and her family.
On Sunday, REV3 is hosting a triathlon in Downtown Knoxville.
