What it costs, head to foot
The Body
Ten days. Nineteen hours on the go, sixteen of them actually moving. Under three hours of sleep a night by the end. The legs get the credit, but this is what is actually happening inside.
Nothing here is a live measurement. The terrain is real, taken from the route file, and the body figures on top of it are modelled from published ranges for multi day mountain efforts. Real readings replace them when the device feed is connected.

Day 1, At Its Hardest
Sleep in the last 24 hours
4h 5m
Brain
Decision making degrades before the legs do. Navigation errors and missed turns are what end rounds like this, not sore quads.
- Perceived effort

Blood oxygen, SpO2
96%
Lungs
The Lake District tops out under a thousand metres, so oxygen saturation stays high. What drags it down here is hard effort and ten nights of broken sleep, not thin air.

Heart rate

Heart
Sixteen hours a day of actual movement, with a working heart rate above 120. The resting rate climbs every night as the body stops recovering between days.

Core temperature

Core
Anything over 39 degrees on a long climb and the body starts shutting the effort down for you. Cooling in a beck is a tactic, not a treat.

Gut
The stomach fails before the legs on most multi day rounds. Eating six thousand calories a day while moving is a skill, and it stops working when you are tired.

Legs
Descending does the damage, not climbing. Every steep drop off a summit tears muscle fibre that will not be repaired before the next one.

Steps today

Feet
Wet feet for ten days straight. Skin softens, splits and blisters under the blisters. Feet are the single most common reason a Wainwright round ends early.

The numbers that tell the real story
Ten Days Of Decline
Watch two lines cross. The resting heart rate climbs every night because the body stops recovering. The heart rate he can actually reach on a climb falls, because there is nothing left to reach with.

Across all ten days
The Full Bill
Highest heart rate
162 bpm
Reached on day one. By day ten he cannot get within fifteen beats of it.
Lowest blood oxygen
93%
The fells are low. It is effort and sleep loss that pull this down, not altitude.
Fluid taken on
73 litres
Beck water, mostly, filtered on the move.
About this data
Altitude and gradient at every point come from the real route file. The physiological figures are modelled, not measured, and every screen on this page says so. They sit inside published ranges for multi day mountain ultra efforts rather than being invented for effect.
The readings live in one database table and are served from /data/vitals.json. Connecting a watch, a chest strap or a pulse oximeter means writing real rows to that table and switching one config flag. Nothing else on this page has to change.
