Sunday marks 20 years of an event that's raised millions of dollars for diabetes research.

The 20th annual Roanoke Walk to Cure Diabetes will be held downtown Sunday afternoon. The walk starts at the Virginia Museum of Transportation at 2:00pm. Registration opens at 12:30.

It's a three mile route, that incorporates part of the Big Lick Greenway.

Last year's walk raised more than a million dollars for the Juvenile Diabetes Research Foundation. The fundraising goal for this year's walk is about $1.2 million.

WDBJ7's own Jean Jadhon will be emcee-ing the event.
