The best way to kick off the holiday season is to add some jingle to your step, literally. Tie some jingle bells to your running shoes and usher in the most festive season of the year by participating in the annual Jingle Bell Run/Walk for Arthritis. Named one of the “most incredible” as well as one of largest holiday-themed races fighting arthritis, the run/walk highly encourages participants to don fabulous, holiday-themed costumes: Santa hats, reindeer antlers, elf shoes — you name it. The fact that the event raises funds to fight arthritis, the leading cause of disability in the U.S., only adds to the merriment. There’s still time to gather a team and find some costumes, late registration starts at 9 am the day of.
