I guess I should have titled it "how fast do you go downhill" or "do you push downhill as hard as you do going uphill"

When I get to the bottom of the hills I get to ride, I'm usually as winded as I was going up them.

I find that on just about every ride I've gone on since I resumed cycling after decades last August (~1100 miles in 4.5 months), I see hardly anyone pedaling downhill, they're all just coasting and sitting upright. I have seen a few people pedaling, even fewer actually pedaling hard.
