I live in the Canary Islands, more concretely, in Gran Canaria. Our towns are pretty spread on the island, and it is really common to live in one town and working in the capital, which on average is approximately 20 minutes by car.
Some of my coworkers come to work by bicycle, they live somewhere near. The one that lives furthest from the office has to make a 30m ride in his bicycle before he arrives at the office.
I was thinking about this idea, the difference is that I should make a 1h 30m trip (estimated by Google Maps): Which is this one: Google maps link
It involves roads without road shoulders and some parts with a cliff on the right (it has a crash barrier).
Being a beginner in long trips (actually never made one that took more than 30 minutes) I don't know if this one is too dangerous for taking it two/three times a week (I work on semi-remote).
