Holiday Run 5k San Diego, San Diego

While all those holiday cookies and treats might be enough incentive for many people to get out and run, the Holiday Run 5K San Diego offers a little something extra. Those that sign up for the race will also get the opportunity to help raise money for worthy causes, such as collecting toys for Toys for Tots. That means runners can feel good not just for getting a little exercise, but because they did something good for their community.
