I am planning on riding around 400 miles from Paris to Grindelwald in Switzerland in the summer over 4 days. I am looking at how I plan the details of the route. I started with Google maps but I did not feel it was giving me what I needed in terms of cycling specific detail (yes I hit the bicycle button !). I then found Komoot which looked better.
So if there are any TR users with advice I would be very grateful.
I used a combination of Strava and Kamoot when I was planning some riding in Norway last year. I used Strava to examine heatmaps and segments for route ideas and as a sanity check while using Komoot to actually draw the route and export it to my device.
Important advice: be sure to confirm you’re not routing yourself over a lake as heatmaps may show activity over lakes which indicate routes used for XC skiing.
Same here. Strava + Komoot
Komoot is awesome, never considered pairing it with Strava heatmaps but it makes a lot of sense so will do in the future.
Strava or RideWithGPS.
Both can create routes you can export to your head unit.
I don’t know komoot, but when I’m in a foreign land planning a long ride I use bing/Apple/google maps a bit, but also local laws, and ask around the various online cycling communities for tips.
It’s worth checking out accommodation options on something like Airbnb as that gives you an idea, from the prices as much as anything else, as where is desirable to be.
I then pick the main roads I want to use and search around cycling and the road names to find any issues local cyclists have.
Good luck! 
Komoot has a great feature in telling you what the road surfaces your ride is going to be on, and also has some great auto routing control.
It really trumps google/apple maps as you may not want to end up on 15km of dirt, and it can be hard to tell in some parts of Aust.
It also links really well with my Wahoo Bolt…
I also find that google street view where available can be a great help.
An old school approach I have found helpful is to call the high end bike shops in the areas you are traveling to. Sometimes there are folks there that are very knowledgeable that can make suggestions. I also ask them about the elite cycling teams in the area and then send an email to the club officers asking for advice. This approach has worked very well for me, including renting bikes, routes to ride and availability of group rides while traveling there if I am interested. I’d also say it is a lot of fun connecting with cyclists from other parts of the country/world.
There is a gold mine I found called plot-a-route https://www.plotaroute.com/.
I am not affiliated with them at all. I used plot a route and osmand to get turn by turn bike directions on my phone and it works really well.
This one is totally free, has different bike profiles (trekking bike, road bike, MTB and more), and one of the best routers. Additonally several different OSM layers. I use this quite heavily.
When planning I store a route as favourite in my browser as there is no user account option. However, for transfer gpx/kml can be downloaded (but not uploaded)
Checking in from Germany: By now I mostly use Naviki. It‘s based on open street maps as far as I know and it does a great job on road bike routes. You can preselect which bike you use, how fast you go, if you prefer direct or fastest route. The road bike option chooses smaller streets where you can ride undisturbed. Cannot recommend it enough!
As alternatives and to double check my routes I tend to use Strava, komoot and the Garmin heatmaps. All of them provide reasonable routing as well.
My routing experience is mostly based in Germany, Austria and Poland, but I‘d guess Switzerland and France will be of equal quality.
My secret tip is Übersichtskarte der Inhalte von www.quaeldich.de It‘s a map service from a Berlin travel agency and they have their qdtp database, which is a curated dataset of GPS tracks that make nice road bike tours. Every route was ridden by a trusted rider, so you can be sure if the track is in there it‘s of decent quality.
For the moment, I use garmin connect in combination with streetview. It can take a lot of time to plan your route though.
For routing in Switzerland, something to look at is SwitzerlandMobility – Cycling in Switzerland - Veloland. There are plenty (an understatement) marked cycling routes (road, mtb) and an ability to draw a route, though I’ve never used that feature. And there’s https://www.myswitzerland.com/en-ch/rennrad.html for more route suggestions.
Thank you I will check that one out too,
Thank you.
I will go to the veloberlin fair on 27th and 28th April and I will check to find companies specilised in map service
I used Komoot for my ride to Switzerland, I used a Garmin 830 and as a combination they were excellent, I certainly recommend Komoot.
I recently rode from John O Groats to Lands End totalling 960 miles and used RIDE with GPS to map the whole route and then downloaded to Garmin 1000. The mapping was easy and very accurate, I would definitely recommend this for mapping routes.
Thanks for the post and congratulations on your LEJOG ride
Excellent well done! How was the ride? Solo? Any drama? 
See lots of guys using Komoot. I always have used RideWithGPS and just stuck with it. What’s better about Komoot that so many riders are using that instead?
