The first 2 kilometres runs false flat downhill onto the first climb. This 2.5 kilometres section averages, while a double digit ramps appears 300 metres before the top.
The course descends for 7 kilometres and continues onto and undulating section before a wall-like intermezzo takes centre stage. A 700 metres ramp with an average gradient of 12.8% opens with 17% and is crested 6.7 kilometres from the finish.
Another false flat downhill leads onto a gradual climbing last kilometre. The incline intensifies in the last few hundred metres and peaks out at 11% just before the line.
