You found the good stuff
.. The "Welcome" trail from the tarmac imo is the best bit of natural single track close to the cbd. Once you have a few runs you can let it rip,.. 160mm bike is perfect for it.. There is another trail that links off it that has a pants shitting chute and step down..
I let it rip a few times with full armour and full face helmet and clocked a 1:07, went back to the car and geared up for an XC ride and rode it again and clocked 1:08, mainly gained at the climb end past the river, but hmm, 34 vs 30km/h, still be fubar-ed if off down there at speed.
Heat stress from pushing back up wasn't fun.
Plankosaurus is going to join me next Saturday at about 3pm for some fun, anyone else wants to join, feel free.
Met some fuckwit on an ebike coming up this track when I was at full noise, one of the monocoque variants with 1500-2000watts, he rode up the steep last bit near the river. These riders are the scum of the earth.
