The course, kilometre by kilometre
Start and finish are 14.5 km apart as the crow flies, so this is a point-to-point course.
It drops 73 metres net, from 186 m at km 2.9 down to 85 m at km 20.6.
The race is held in Toronto, Canada, in May, on tarmac throughout.
Elevation gain and climbs
162 metres up and 235 down across 2 climbs worth the name. No single one decides the race; the sum of them does.
The hardest stretch runs from km 5.3 to 6.0: 38 metres at 5.4 % on average. It comes early enough to take on fresh legs.
The gradient model puts this course at 0.30 % flat-equivalent — faster than flat, on paper. What it does not model: 19 % of the course runs downhill, and 235 metres of descent load the quadriceps long before the first climb arrives.
Against a 3:30 target the terrain costs about 1 minute compared with a flat loop. Adjust for gradient and what remains is what the legs actually paid.
The route on the map
The course covers 14.5 km of ground between start and finish and never returns to where it began.
The GPX data of this course
The smoothed profile is stored every 50 metres: 845 points with latitude, longitude, elevation and gradient. The elevations come from the course file itself, median-filtered and smoothed with Savitzky-Golay.
We do not hand this course out as a file: the line comes from a third-party source and is not ours to pass on. Once a course is built from runners’ own recordings, the file appears here.
