Toronto's half marathon courses make full use of the city's trail networks and waterfront, creating mostly flat routes perfect for personal bests. The 21.1-kilometre distance allows competitors to experience multiple Toronto neighbourhoods and distinctive urban landscapes in a single event.
The biggest events tend to take place in Spring and Fall, typically starting downtown before heading along the Martin Goodman Trail or into the Don Valley system. Many routes incorporate out-and-back sections along the waterfront, providing Lake Ontario views and consistent terrain - ideal for keeping a great pace.
Winter maintains a limited half marathon schedule with occasional "cold weather warrior" events, while summer races typically start early to avoid humidity and urban heat effects.
