So there's always things that you discover along the way that make touring that little bit easier.
here are some of the technology things that have saved me a few times, so far.
1. Warmshowers - obvious one, but it's fricking amazing.
2. Offline cycle route apps (so good) by Stuart Grey. He has them for UK, France, Netherlands, Belgium, Germany, Denmark. They're £3 each from apple/android app stores or you can buy them in bundles for £5. They use your phone's free GPS for location. They also show bike shops, cafes and pubs/bars.
3. I use Maps.ME - so so so good because you download the areas you need to use and it gives you super good directions, like a GPS. I often look at vague routes on Bikemap (another app) and then follow smaller roads on maps.me because I like the tiny roads :) An awesome feature I found of Maps.ME is is you search 'drinking water' it brings up all the water taps. I usually bookmark them all on my route so I never get caught short.
4. Or failing that, navigating with offline google maps and GPS - better for specific landmarks in cities, but I find it doesn't have cycling directions in many countries.
5. I use methylated spirits in my trangia stove, and this list of fuel names by country saved me on more than a few occasions. The NAFAA (North American Fire Arts association) also has a good, more updated list, that replaces petrol with paraffin.
