Wednesday I left Orlando for Atlanta. Breaking the record for my longest ride. I've done loads of 2.5 hour rides on roads but never more. I would like to take a trip to Colorado to leave some of my dads ashes at one of his favorite camping sites. So this was to see if I can do it.
It kicked my ass. I have some training to do. It is almost a 7 hour drive. First day I didn't leave early enough and the heat bit me. Yesterday, Thursday I woke up sick with a short virus. Headed home today stupid early but much more comfortable. Really wanted to get two long drive days in a row under my belt.
Thinking that 5 hours per day might be a better decision for my long trip. It really took it out of me.
Good on you for taking care of your Dad. There is some closure in spreading even some of the ashes. I hope that helps you with the loss.
I'm one of those nuts that does long distance riding and endurance rallies. You work up to the longer days, figuring out the things that bug you and fixing them as they come up to make your days easier. There is some stamina that builds up as well, but there are a lot of little things you can do to keep yourself more comfortable and make it easier as well as more enjoyable. Hydration is key, you must stay hydrated or your brain slows down and your muscles tighten up and you can suffer cramps. Another issue is blood flow, especially in the limbs, so you need to move around, not just "sit there, twist that". No harm in getting off the bike now and then either! 600 miles can be a really relaxed, fun 12 hour day of riding. Start early, have a nice lunch, take some photos, and stop when you're done at a hotel that has food in walkable range.

Here is some very good advice on keeping cool while riding. It works best with their products, but you can get some benefits with normal clothing too. I do use LDComfort under my gear when riding any kind of distance, it just works better than anything else I've tried. A little expensive, but it lasts a very long time too. Quality stuff.
