Runners taking part in the Canada Army Run were urged not to go for a personal best with high temperatures in the forecast.
Organizers of the major racing event took to Facebook Saturday afternoon issuing a warning to participants about the potential dangers of running in the heat. Temperatures hit more than 35 degrees with the humidex Sunday, but luckily the race went on without a hitch.
Roughly 22,000 people laced up for the 10th annual Canada Army Run. To celebrate its anniversary and for Canada's 150th two new challenges were added, including a 10 km race.
Prime Minister Justin Trudeau took part in the 5km race, becoming the first sitting prime minister to run. Canada's Defence Minister Harjit Sajjan also ran.
Due to the high heat, runners were encouraged to pace themselves and to wear lightweight clothing. Spectators along the route were also asked to bring out their hoses and sprinklers to help keep runners cool.
