How it works
Every mile of it is uphill.
One lap: 2.3 miles and 2,310 vertical feet at a 19% average grade. The gondola takes you down; only your legs take you up. Do that thirteen times, inside 36 hours.

The ascent
Scroll down. He went up.
The whole climb on one clock — 32 hours across, 30,030 feet tall. The slope of each step is his real pace; flat stretches are gondola rides and breaks. The staircase only ever climbs.

Minutes per lap
The mountain never got steeper. The legs got heavier.
The last lap took twice as long as the first. He climbed it anyway.
† Lap 1: Bruce forgot to start his lap timer until roughly halfway up, so its first 27 minutes are reconstructed from the 6:00 AM gun. The hatched piece is the reconstruction. Every other number on this page is straight off the clock.
The night
He watched the sun set and rise from the same trail.
Sunset just after 9 PM Friday. Sunrise just before 6 AM Saturday. In between: three full laps on a headlamp.

25h 18m of these 32 hours were spent climbing — he was off his feet for less than 7. The longest he ever stopped was 1h 53m, at 3:30 AM. That was the sleep.

What it cost the body
WHOOP scores daily strain on a logarithmic scale that tops out at 21. Day one read 20.7. That's not a high score — that's the gauge, pegged.
His heart rate never got to go home.
WHOOP's running average heart rate for the day, sampled at each summit. It only ever went one way.
MT. EVEREST — 29,029 FT
Saturday, early afternoon, lap 13 — somewhere on that stretch of trail he passed the summit height of Mount Everest. Then he kept climbing.
Final summit
1:55 PM Saturday — 4h 05m inside the 36-hour cutoff.
