Official Sun Safety App — kept runners informed on UV exposure through summer training and on race morning.
Race-day by the numbers
SunUp was the Official Sun Safety App of the 2026 Mercedes-Benz Oakville Bronte Harbour Classic 5K.
SunUp delivers real-time UV index, air quality, and personalized burn time based on your skin type, age, and activity — so runners can train and race safely outdoors, especially through summer race season. With a 48-hour forecast, family mode, and hundreds of contextual tips, it turns “is it safe to be out right now?” into a question runners can actually answer. On a sunny Father’s Day morning by the water, that’s exactly the kind of partner a race wants in its corner.
Why we love having them at the Classic
A June race on open waterfront lives and dies by the sun, and SunUp is our own answer to it. Built within the organizing family by GearTOP, it let us hand every runner a free, personalized way to train through the summer without guessing at UV.
