Thats the way I designed todays ride, the "big wave" being the ascent of Belchen, or at least as far as a road bike would go. So I stayed on the French side of the Rhine for the first 50km, the idea being to "paddle out" down the river then swing in to the east and ride the big Schwarzwald mountains from the north back home.
This section really is a time triallers dream (ie flat and boring), so little traffic it was easy to cruise along and be disappointed when my computer said 32km was below my average speed.
I was aiming to the Rhine at a place called Fessenheim. Tell tale signs alerted me before I arrived at this place, seldom used rail lines, large amounts of barbed wire and many security cameras around the perimeter that this was not a normal hydro electric power station. Only when I got to the main gates did I realise that yes, this is a nuclear power plant, and the oldest operating one in France - really not far from Basel and many other populated areas so not surprising to discover later about the many campaigns for this place to close down.


3 smaller waves continued in the set, the climb out of Zell being the most significant and soon I was fast approaching the Rhine to the south and with it the Swiss border. Here I was fortunate to be overtaken by a speedy pair, and as I had been debating with myself whether to ride home on the Swiss or German side of the river, sticking on their wheel was clearly the best option and so helped the average speed for the day to a respectable 26.4kph for the 172km ride. Strava says 3042m gain, mapmyride says 1968m but as I have joined the Strava Classic Climbing challenge I am happy they are giving away as many meters of ascent as they do.
