I just did the STP last weekend and you sound like you're in way better shape than I am. The first 100 miles are not very hilly, it starts out pretty flat and then around mile 40 there is one large-ish hill that you actually have to gear down for, followed by gradual long 1-2% inclines and some rolling hills. The second 100 miles is certainly hillier, there are a handful of short steeper hills and then the last 50 miles are rolling hills all the way to Portland.Originally Posted by betagirl
Considering our topography here in the Pacific NW is fairly bumpy, this ride probably does follow the smoothest possible path from Seattle to Portland. It's certainly not as flat as some people made it sound, but it's certainly not a hill ride.
