Hey, go for a ride. I don't think 250 miles is too much, especially slabbing it on those western highways. You should be able to get that in easily during daylight hours with plenty of resting time in between.

You might want to consider heated gear, especially a jacket liner. And heated gloves if you don't have heated grips. I've had good luck with Gerbings, but I'm sure other brands are fine also. Heated gear makes riding the slab in 40 to 55 degree weather a whole different experience than without it.
