Last days I was on Tenerife, it was my first longer vacation in a year. One day I decided to rent a bike and go from city when I was (Puerto de la Cruz, north Tenerife) to Teide volcano. It was something amazing: only 36 kilometers one way, but all time up. Close to 2100 meters up in such distance – whow! It was the longest climb I ever made. Not the most difficult, because average slope was about 4-5%, maximum about 9%. On Karkonosze Pass I ride climbs more than 25% in this year. But this one was also difficult by length: almost 3 hours of intensive riding… Amazing, real. And also, with amazing views – check my Strava to see them.
