Climbing repeats

Pouring rain, couldn't stand another day on the trainer so I took out my old bike. No snap, hard time with the heart rate again. Felt like I was climbing hard but the highest I could get the HR was 156 during the climb. Usually I keep it right at 159 and have to ease off. Sunday's ride was harder than I thought apparently. Could be too many miles last week.
