The course is over 3 laps of a 1km circuit.  The first 500 metres or so are flat.  At about the 500m mark, there is a sharp little uphill section for about 20 metres followed by a longer straight section of about 300 metres which goes very slightly uphill. The road then turns sharply left and the next 200 metres  to the 1km / 2km / Finish are all downhill.
