This hill starts with a fast left hand turn and ends with a sharp right followed imediately by a sharp left (the sharp left is optional though). Inbetween that is a long straight where it's a bit slow (max speed of about 65km/h) so you need a good tuck which you must maintain around the corners to follow. When approaching the chicane at the end it may be necessary to foot break depending on your cornering/sliding skills. The relatively slow speeds in the middle sections make drafting a lot of fun. The traffic on this road is not an issue at all since the speed limit is 40km/h so if you stay in your lane you're safe.
