When I was trying to do the EuroVelo 15 route just over two years ago, it was really obvious Google Maps thought I could maintain sprint speeds all day long.
It also didn’t understand the impact of hills, which is why I cut the attempt short (1080 km) after it redirected me up a Swiss hill instead of keeping me close to the Rhine.
I would’ve preferred a GPX to follow, but I couldn’t find any of that route.
Two years ago there were definitely GPXes for that route on RideWithGPS - I don't know if https://ridewithgps.com/routes/13794818 (2016) was the one I followed or not, but it looks like it would work.
(Also, it's well-signposted, and in any case the whole point of the route is to follow the biggest river in Europe, you don't need a lot of navigational aids).
Thanks, I’ll use that if I get a chance to do the reminder of the route.
I took a wrong turn in Eiken, which isn’t directly next to the river, and didn’t notice my mistake until I’d already exhausted myself. The nice scenery was a pleasant but unfortunate distraction.
