When you're carrying water, make sure you've got at least two bottles on the bike. Three is better. And, if you're in dry country with few water stops along the way, pack some more. Water is heavy, but running out on a hot day can be dangerous.

You don't need to pack much food because you can stop along the way and buy what you need for a day or two.

When you're looking for camping equipment, look for the stuff backpackers would use. Small and light should be your mantra.

When you're packing clothing, look for things that are light and versatile. Choose light cotton pants instead of jeans. Look for shoes that you can wear on and off the bike, rather than cycling shoes that do not work for walking. Carrying a second pair of shoes will add weight. You can get shoes that accept the pedal cleats but are also decent for walking. Don't bring a lot of changes of clothing. Everything you bring will add weight.

Prepare for rough weather because you will encounter it on a 40-day tour. Bring some rain gear and sweats or polar fleece clothing for cold weather. Also, because you're camping and because you're going through the mountains, bring a toque or knitted hat with you. You may need it at night. Some parts of Colorado can get cold at night, even in summer.
