Yeah. I’m an aged mountain biker. Very mediocre. But when I travel to low altitude, I feel like Superman when I ride.

I live at 5000 ft now, but in my 30s I lived and slept at 9000 but did all my rides near 5000. That was an amazing time for my fitness. I could go hard at “low” altitude but recover at high which is what my body adapted for.
