Tour Divide Prep

I really don't know how to prep for a ride like the Tour Divide except to be in decent shape for it and have some saddle time in. My situation is a bit odd. 1.) I don't live in the USA. I live in a country where it is becoming increasingly dangerous to live in, much less ride a bicycle in. 2.) I commute to work 180 km every Sunday afternoon and return home Friday night. My bicycle stays at home in Lecheria 3.) The town where I work is too sketchy and dangerous to ride [see all of the above...].

So here is what I am doing. 1.) Converted my Merlin back into a geared bike so I can ride farther and faster on the weekends [see pic]. 2.) I ride at least 2 hours each on Saturday and Sunday. On Saturdays I usually have other things to do, honey-do stuff, plus spending time with my lovely wife. 3.) Hitting the gym during the week. I ride the spin bike for 30 minutes, and lift weights. 4.) I am trying to eat better.

I am approaching this more as a tour than a race. I just want to enjoy myself, but that means being prepared. I've done quite a bit of touring in my day, including offroad mtn bike touring. I am buying some new gear, prepping my Litespeed the best I can from 3000 miles away and hopefully staying strong and healthy.
