Elite athletes will be taking over city streets this Sunday for the first-ever Ironman Canada Triathlon held in Ottawa.

The triathlon begins with a 3.8-kilometre two-loop swim in the Ottawa River before athletes embark on a 180-kilometre bike ride along National Capital Commission (NCC) and city roads. Finally, a marathon run will take participants through Ottawa streets and around Parliament Hill.

Participants have 17 hours to complete the event.

The City of Ottawa says several roads and bridges will be closed as early as 3 a.m. Sunday to prepare for and hold the event.
