Hill turtle too
I am always getting passed or dropped on hills. At first I blamed it on my bike, wider tires, smaller wheels, heavier. (the bike not me)
Then I graduated to a road bike, smaller tires, bigger wheels, lighter. (not me - the bike - I gained a few pounds so we are now about even again
I was still getting passed.
I went to the doctor "Dr, Dr, what can I do ? ? I can't breathe when I climb hills,please make my lungs better - I want to be able to climb a hill without dying"
Lots of tests later I discovered I was functioning on 65% lung capacity and was chronic asthmatic (I used to just be exercised induced). Very expensive medicine later my lungs are much better although still not perfect
I started to do weight training in December and riding a lot in April, again with the only goal of climbing hills easier. Every time I went out for a ride I tried to climb at least one good hill - I thought "this is only 10 minutes of my life"
I still can't breathe and huff and puff all the way up. My friends are no longer quite so concerned at my condition - very red face and heavy breathing. I still get passed regularly, BUT at the beginning of the summer I could only go 6.5 tops up my measuring stick hill and last week I went up at 7.0
Progress - Not perfection
Hang in there, I wish I could say they get easier but they don't - you just get faster and the pain goes away quicker
It's about the journey and being in the moment, not about the destination
