I've never done fast paced self supported touring. I did the divide route this summer would be ok physically to do that mileage, but I've nver done any "lite weight" touring so I feel like I'd be a burden on you guys, I'm not too familiar with the route, but if you'd be willing to inform me on the necessities / packing list, I think I may be able to join since I have all the gear already.
We've only ITT'd the CTR and done a couple of road tours, so I think you've definitely got us beat with a Divide under your belt. We'll likely carry no more than one day supply of food and water at a time. It seems as if there are plenty of stops along the way for resupply. This trackleaders map gives a nice overview of the route if you feel like taking a look:

As for clothing, I'll likely be bringing, arm/leg warmers, rain gear (pants, jacket, sock covers), thick Smartwool socks, stocking cap, gloves, etc. I plan on just using my rain gear in the morning to keep me warm and then jumping out of it before I start pouring sweat in it (seemed to work on the CTR on the colder starts). The route doesn't exceed 5800 feet of elevation, so nights won't get too cold (assuming fair weather and the possession of a decent sleeping bag and bivy/tent). Again, hoping for little to no snow, but we shall see what mother nature has in store as the departure date approaches.
