I’m guessing it’ll be your first time on the island? You’re in for a treat!! Beautiful doesn’t do it justice.
I think that the sheer variety will help you maximise the trip, without the need to adjust your training. Coastal rides for a nice easy day, over to Puig Major when you fancy a day with some lumps. There is nothing too taxing on the island so you’ll be able to put mountain days back-to-back with relative ease.
Just be careful if it rains. The mountain roads are like silk in the dry and ice in the wet. Hopefully you won’t get any wet days.
