I guess I'd normally consider a lap to be the following:
Start at Lamberts track on Logan Park track.
- Up Lower Buckle Trail to Upper Buckle trail at the East-West Break. Right at EW, then left north onto the fire trail until it reenters singletrack at Upper Buckle.
- Follow Upper Buckle up to the north hill, then down the firetrail descent, before a left onto the gravel firetrail before quickly veering left back into - Upper Buckle Trail (which you can't really do anymore because it's rutted and has been blocked off with deadfall, so you have to go around).
- Follow Upper Buckle all the way to the EWB Fire Trail, go left into the singletrack instead of up the lactic acid inducing hill.
- Take a left once at the top of the singletrack to continue onto Middle Trail - you're now going South.
- Continue all the way down middle trail and continue along Red Gum trail until you get to where the M2006 course joins - follow it straight on (ie, don't ride against the course direction) and go left at the top of the hill onto the firetrail.
- Join onto the singletrack where it goes left, and go down towards the general direction of Hug Trail.
- All the way down Hug trail until you get to the South Break where Blair Witch starts - don't go onto Blair Witch, instead go down the hill to the left.
At the base of the hill go right into the Lower Blair Witch singletrack, then continue through Blair Witch until Lake Circuit at the bottom of the dam wall.
- Don't follow Lake Circuit - instead go down behind the dam wall, along the gravel fireroad, all the way up to the rangers station.
- Following the trail up the southeast side until you get back to the Horsewood Road carpark.
- Continue up the Logan Park firetail to the point you started.
That sounds pretty straightforward doesn't it? Holy crap did I just type all that?
