Here is my thoughts on a couple of questions I have seen on the thread and other items of interest:
Tires: I have had good luck using the Ikon's last year on my 750 race as well as using the Ikons in 2014 on the AZTR 300 and on the CTR in 2013. A solid tire with no issues. I had plenty of tread left on them after the 750. No sidewall cuts at all.
Bike: Kokopelli Ti 29er hardtail single speed with a 120mm fork in the front.. Used a 32x23 on the 750. 32x22 on the 300. Was very happy to have that spinning gear. The asphalt road to Jacob lake was a bit mind numbing but at that point who cares. I was almost finished.
Pack: I don't use a pack for bikepacking. I shipped an Osprey pack Stratos 36 (same one John S used) to the GC post office and my trail running shoes for the 15 hour journey all night through the ditch. I used it twice. Once on a practice HAB in the ditch and for the race. It's for sale if anybody is interested. It's orange.
I only filtered water once.
Make sure your brakes are well bled.
Shoes: Giro Terraduros. Only a slight delam at the top of the left toe and lasted the entire race. Warranty replacement afterwards.
Switch the start direction every other year like the CTR. Just my thoughts as I wont do it again. Ha!
I saw at least two caches for racers that had Gatorade and cokes. It was nice to see this trail magic. But I know trash can be a problem. It's a nice gesture. I saw some card board signs too which was uplifting at times on Jacobs Cross trail or whatever its called.
Here is my blog write-up:
