The race for human capacity

CapRac is a timed competition built around the human capacities being quietly challenged by automation — memory, strength, empathy, imagination, and judgment. Every station is timed. Every difficulty level is faced by every athlete. Nobody knows where the hard one lands until they arrive.

The Problem

We lose capacities we stop using... and we've stopped using a lot in the age of AI

A generation of tools built to think, remember, and decide for us has made daily life easier — and made the underlying human skill optional. The research is no longer speculative.

The Five Capacities

Everything erodes differently. So everything is trained differently.

CapRac scores five distinct human capacities — not as vague wellness pillars, but as specific, measurable, trainable behaviors.

01
Mind
Recall and reasoning without a crutch — memory under fatigue, logic under the clock.
02
Body
Strength and conditioning — the oldest capacity in the set, and the one automation erodes most visibly.
03
Heart
Reading and responding to another human accurately, under time pressure — a skill no algorithm has replaced, and few now practice.
04
Creativity
Original output under real constraint — timed, judged only on whether it's genuinely new.
05
Agency
Catching a wrong suggestion fast. Committing to a real decision under ambiguity. The capacity automation erodes most silently — and the one CapRac was built to measure first.
The Mechanic

You will face every difficulty. You won't know where.

Ten stations, ten difficulty levels — one through ten, each used exactly once. The mapping is shuffled before every race and revealed only on arrival at each station. Total difficulty is identical for every athlete. What differs is whether you can handle not knowing where the weight will land.

Formats

One mechanic. Three ways in.

Entry

CapRac Lite

Mind, Body, Heart — six stations. The on-ramp format, built for first-timers and gyms programming toward the full race.

6 stations · 3 capacities
Ranked

CapRac Global

All five capacities, the standard station library. Fully comparable across every licensed city — one time, one leaderboard, worldwide.

10 stations · 5 capacities
Cultural

CapRac Local

All five capacities, region-specific substations — fencing in Paris, ballet in the Creativity pillar. Same clock, a different soul in every city.

10 stations · city-specific
First Race

The pilot runs at Cambridge.

CapRac's first race is being built and tested at the University of Cambridge — a population fluent in exactly the tools this format is a response to, and a research environment built to measure what changes when people train for it.

Built by someone who studies this for a living.

CapRac comes out of Shriya's research into relational computing — how technology and human relationships shape each other — combined with a competitive athletic background (archery, fencing) and years spent building products at the intersection of memory, connection, and human capacity. CapRac is the physical, competitive expression of a question she's spent years researching: not whether AI is powerful, but what it's quietly costing the humans who rely on it.
