I have biked mount teidie a couple of times you will need to be fit it’s a tough climb , especially if you climb from los gigantis and I would recommend Maria Lanza suits and spa in los cristianos 4 star + with Thompson’s top class hotel and food is great , join the gym and you can do a spinning class under water, great fun great gym €40 a week to use,you will need the gym when you see all the food
