About
Every year, the Ottawa Half Marathon presented by Desjardins is the weekend’s most popular and fastest sell-out event. This course is fast and relatively flat, making it great for personal bests and runners trying the distance for the first time. It takes runners past historic landmarks and through vibrant neighbourhoods of the nation’s capital, finishing near downtown with an upbeat festival atmosphere.
Catering & aid stations
Water/Xact hydration stations are set up approximately every 3K with Cherry Berry or Lightly Lemon. An Xact Nutrition station is located before the water stations at 15.25K in a mix of fruit bars. Cooling and misting stations available on-course. Portable toilets at every water station.
