Be sure to stay well hydrated, sports drinks with added electrolytes work well. Eat a couple bananas everyday for potassium. Do a good stretch in the morning, evening, and a few basic stretches during the day. That should get ya good to go.....still have the girl rub ya down though
That's how I do it, and I'm 41, ride 7-10 days straight on my trips to Co. open to close pretty much non-stop except for a few beer breaks here and there. I also ride my local hill pretty much every weekend, so I stay in shape.
