Hello! I'm also in GJ! Welcome to BF!
I hadn't trained much for my tours. I commute around town a lot with panniers also. On the first couple of days of the tour I try to take it easy, 20-30 miles. Delta is a good first day. Montrose was a bit too far for a first day. I did Gateway for a first day once and it wasn't too bad, lots of downhill after the divide in Unaweep Canyon.
Are you touring out your door? We have done a few 1-2 week tours right out or door and there are some great rides nearby.
