I've been wanting to do this route for a while now, but the timing never seemed to work out. Oregon Cascades 100 got canceled so I decided that it was a good time to try the TCT. Huge thanks to Cryptic and Jessica for their great information and CalTopo links. The information for water was still very much correct. I started from the north and went south at 1:27 am with hopes of making it out in the light. The first 47 or so miles were amazing trail with great views and fairly plentiful water. There was a 15 or so mile dry section. After that the trail dips down into canyons and the going slows waaaaaaaay down. The trail is harder to follow and there is a ton of bushwhacking and river crossing. Perk is that you constantly have water and don't need to worry about that anymore. Downside is it is hard to run, painful and easy to get lost. I wore zip off pants and am pretty sure I wouldn't have skin on my legs right now if I hadn't. I with I would have brought gaiters since there were miles of fox tails that tore up my ankles. Also be on the lookout for mountain lions. I encountered one with roughly 2 miles to go on the trail. We had a couple minute standoff as we were in a canyon with no way around each other. Eventually the lion went up some cliffs after lots of yells, rock banging, and grunts from me.
It's truly an amazing trail and I would highly recommend it to anyone looking for 66 miles of single track with no one else around. You really get the feeling of being alone out there. The last 20 miles were definitely rough and not that fun in the dark. If you can plan it to do those in the light I would bet it'll be more enjoyable (but still don't assume you are going to be moving fast!).
I ended up doing this completely solo which meant leaving a bike, tent, soup, and sleeping bag for myself at the south end. Luckily I was able to hitch a ride after about 20 miles on the bike back to the trail head from a guy at a gas station (thanks Woody!)
