It’s been hugely sanitised in recent years. The stump mentioned above has been cut out a fair bit, and there was another one just before the switch to fireroad at the top, which has also been removed.
I’m a big fan of the course, one of my favorites. Definitely needs to be attacked to get the reward from it. Seems to come alive at around the 1 hour kind of lap times.
The DH is doable on a trail bike. There’s nothing you can’t just roll down (even the road crossing has a chicken run that looks more intimidating than it actually is). It’s more that the stuff on it is quite sizable by trail centre standards and the gradient is there to keep things feeling a bit fast.
I’ve ridden it on a Five and a Patriot, the Five was entertaining but a bit sketchy to really let go (140mm 32s and Mono Minis to be fair). The Patriot made it waaaay too easy. Alpine 160 would be ideal.
