It's all treats and no tricks at the annual Trek And Treat 5K. Runners don their Halloween best for this race, which takes place through the darkened trails of Oakville. Armed with headlamps and flashlights, racers trek past spooky Halloween decorations and pumpkin trail markers. Once they've survived the dark journey, participants are welcomed to a post-race party where they can enjoy pizza, hot chocolate, and plenty of other treats.
