The course, kilometre by kilometre

Start and finish are 1245 metres apart: the Bank of America Chicago Marathon is a loop.

Highest and lowest point are 7 metres apart, and start and finish are at practically the same height.

The race is held in Chicago, United States, in October, on tarmac throughout.

Elevation gain and climbs

33 metres of climbing over the full distance, with 99 % of the course under one per cent gradient. This is about as flat as a marathon gets.

Against a 3:30 target the terrain costs effectively nothing — under half a minute. Adjust for gradient and what remains is what the legs actually paid.

The route on the map

The course runs as a loop through Chicago and finishes 1245 metres from where it started.

The GPX data of this course

The smoothed profile is stored every 50 metres: 845 points with latitude, longitude, elevation and gradient. The elevations here do not come from the course file but from a terrain model: the ones in the original were unusable.

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.
