So I went out today to do a climb. I usually climb 2x a week. Nothing major as I am a recovering smoker/drinker. Anyways as I started the climb I got about half way up and my heart was going to explode or at least getting really close to my max. I have never backed off this climb. I've been riding a steady 130-150 miles a week. So what gives? Is it an off day or is something that is going to be long term?
Thanks for your help.
