I had so much fun running a vertical mile of stadium stairs last year
I decided to do it again.
It was muggy to start, and I ran a faster split than any time last year (<15) but probably because there were other people. Then I overheated, had to drink a lot of water, and slowed down. Finished about 1:30 behind last year, not bad given the warmer weather.
Didn't go hard, but L2 pushing in to L3 whenever I ran.
Then ran the last two sections with someone else finishing. Total of 6 of us, more vert than Everest.
