Okay so this summer me and my best friend are planning a bike tour starting in Central Texas, headed west through NM and AZ towards California,continue to head north through Oregon and Washington, head west into Idaho and up to Glacier National Park then head south towards Yellowstone, Utah and then finally Colorado. We have May-August to do this so I'm hoping we can squeeze everything in. So far I've been doing as much research/prepartion as I can from reading touring forums and the bicycle traveler's blueprint to get as much information as I can.

Right now my main concern is biking through the desert safely in the summer heat. Is this possible or totally ill-advised and foolish? We want to first go to Carlsbad caverns, bike through the national park into Lincoln National park/Ruidoso, head west towards I-85 and take it north towards Albuquerque. From there we plan to continue west towards Flagstaff/The grand canyon, head towards Las Vegas and then finally through Death Valley into California.

I know this sounds ambitious but we plan to train extensively for the next 5 months to be as best prepared physically as we possibly can. We are carefully planning a route so we can stop in a town/park and refill on water and food every 1-2 days. Still, mother nature is not to be taken lightly and I want to know if anyone else has done anything like this before or let me know if we are completely over our head. Also, the other issue is that in order to finish the trip in time we are looking at an average of 80-90 miles a day. We have never done a bike tour before and I'm not sure the difficulty level in doing this in extreme heat. Any advice on this trip would be greatly appreciated. Thanks guys
