I decided to create a hilly 12 mile loop to increase my Hill strength.
Let's just say I only completed 10 of the 12 miles as I had to turn back due to it getting too hard to keep going.
Going to change my 53/39 cranked for 48/34 tomorrow and will give it another go. Guess if that still isn't enough I may have to go to a larger chain ring on the rear. Currently 28.I stopped when the gradient hit 16%
Once I have this tackled I'm sure it will help my strength and lungs.
