There are two tracks here, Gully is the old original and more technical track. 

Slightly closer to the hillside, a newish track has been built which is fast and flowy, Tu Meke.

All Strava results only refer to Gully as it doesn't recognise TuMeke. So don't be disappointed if your Strava says you  are a minute slower than everyone else down Gully, its because they would have been riding the fast track, TuMeke
