Cool. 200 watts average for such a long ride is awesome.

I have a PT Pro+ hub in a Mavic Open pro wheel but this year rode a new-to-me bike with a Quarq Cinqo crank based power meter. Training Peaks WKO+ says 175 watts for the ride (which includes zero-averaging/coasting, but does not include pauses/rest stops). I spent nearly 11 hours on the saddle. Stopped too much/too long. But can't complain. Everything went smoothly and I was significantly faster and stronger than last year.
