Even if you're not a member of the Seattle Randonneurs, you can download the route sheets for their Permanents routes.
Go ride
The Alplet 100k,
The Alplet Plus 150K, and
The Alps 200k.
There's your hill training. You can curse my name as you ride each one.
I don't see an issue with riding the STP 2 weeks before RAMROD, but our club does all sorts of crazy back-to-back weekends of long distances. YMMV.
