Do a few long back to back training days.

Leave early on the first day, so that you are getting to your destination fairly early.

When you get there - eat, take a shower, take a nap, get back up and eat, go to sleep (even if it is only 6 o'clock...), get up the next morning and eat some more (more than normal too)...

Get a massage at your overnight stop, if its offered.

Expect some soreness/stiffness/sluggishness at the start of the next day. It should pass once you get warmed up and going again.

Be extra careful to fuel the second day - you're reserves will already be low, so eating and drinking will be even more important.
