Rhine Cycle Route

I have been looking at some of the EuroVelo routes hoping to do a 2019 trip starting in Spain and ending in Avignon. Have you been able to find more detailed maps for this route?

4 days? FOUR DAYS! hahaha
My wife and I cycled the Rhine 2 years ago from Oberalppass to Arnhem, then kicked up to Utrecht/Amsterdam/Ijmuiden for the Newcastle ferry. It was a totally brilliant tour, we thoroughly enjoyed it.
But we took 25 days, so any advice we have is probably not relevant to your headlong dash! Just remember that much of it is on cycle path and it goes through many cities and towns (and you need to eat and sleep) so keeping up 250 miles/day will be a helluva challenge however fit you are.

Good call. It’s all relatively flat until your final day that will take you over the pass by Oberalppass. Key will be getting your route sorted onto the Garmin (or whatever) in advance as stopping to check navigation slows progress. If all else fails, travelling with bike on German and Swiss trains is an absolute breeze!
Good luck and do post back to let us know how it went.

p.s. this is not how you will do it :

Advance routing and slowness of crossing cities I've mentioned, so here's a quick brain-dump: Cycle paths are generally first class and fast; most of the unpaved sections are better surfaces than a lot of our country roads! Most are paved, however, and are well signposted but probably best not to ride on skinny racing tyres as punctures are another time thief. Places to eat are numerous, but country bakeries tend to shut for lunch so beware. Duisberg was a complete dump, the only place we felt uncomfortable cycling through and the only section where signage disappeared. Our route crossed the Rhine a few times by ferry (we followed the Cicero guide) so ferry waits, though brief, also can slow progress. We were caught out by floods too ... had to wade through the high street of a small town outside Basel, and one ferry didn't run due to flooded approach road and jetty (hence a 20km stretch covered by an unplanned train journey into Karlsruhe). Switzerland is eye-wateringly expensive! We booked ahead using the website https://www.bettundbike.de/en/
It guarantees secure bike storage. I guess you'll be winging it depending on how far you get each day. It looks like there's even a Bett+Bike app now so you should easily be able to spot nearby accommodation when you've had enough for the day. Luxury! I loaded openstreet mapping onto my Garmin GPSMap62 from https://openmtbmap.org/tutorials/send_maps/ via Garmin Basecamp and, as back-up, loaded the requisite map tiles onto my Viewranger app on my iphone along with a .gpx track of the route. Nowadays your data allowance is usable in Europe just like at home, so preloading is not so necessary.

Hope this helps, if I think of anything else I'll post again.

p.s. we are flying to Basel in July, cycling back along the Rhine then cutting north to Tuttlingen and following the Danube to Vienna. At a more relaxed pace than you, of course ;-)

It is a beatiful bike trip indeed.
I have done it on 1Wheel and drove back (upwards) aboard a cargo ship.
