I got into cycling in July 2020.
Coming from bodybuilding, I decided to focus on building my endurance with longish (for me) outdoor rides. I currently commit to two rides per week, 3 when I have the time off from work.
When looking at my heart rate analysis, I spend about 50% of my rides in Z3 (tempo) and 50% of my rides in Z2. My goal is to get fitter and better at the sport of cycling. Should I be slowing things down and aiming for longer slow rides? Or should I keep doing my 2 to 3 hour rides at this intensity?
Thank you for the input!
