Running

running at 10k ft (3000m) altitude the past 3 days was really interesting

did a 5 mile (8km), +410ft elevation (125m) run at what felt like slightly faster than threshold pace, and it ended up being 6:51/mi (4:16/km)

first run back at ground level: 21.1km in 1:48 (8:14/mi = 5:07/km) @ 128 BPM heart rate

still (obviously) kept the streak alive 😤

(919 days)

I think so. At 80 the hospital put you on oxygen mask at high flows…
