For an article on the cycle ride I did in Spain in October, I logged on to map my ride. It’s a bit fiddly for the free version and I had to start over twice, however, the route follows the roads I took pretty accurately now. In the 75 km I’d cycled an accumulated height gain of over 1000 metres. Then I discovered the little 3D button on the right of the map. It is a small window but gives a great feel of a helicopter ride over my route. It revealed a few wriggles through housing estates I don’t remember doing but overall it is faithful. It takes 14 minutes from start to finish. This is faster than the 6 hours it took me even on a carbon fibre race bike! Give it a go, it’s free!
I might use this resource again.
