My goal for the year is to do San Francisco's Adventure Series on an upright, so I've been trying to avoid falling back on the recumbent.

My Selle SMP Drakon on my road bike is still working well. In March I did a 130, 300, 200, and 400 in that order, and at least for the 300 and 400 I second guessed the upright choice as I drove to the start, but the Selle SMP worked out well.
In April it'll be a Fleche, a 200 or 300K, then a 600K, and I'm hopeful the upright will be fine.
