Activity intelligence for competitive cycling

Certified data. A new model.
A new way to see.

Competitive racing produces the closest thing to lab-controlled data that exists at population scale: maximal efforts, consistent protocols, independent device recordings, hundreds of thousands of athletes. The data has always been there. No one built the tools to read it.

RaceProof compiles, cross-references, and certifies that data into a single authoritative record. Then it analyzes what certified data makes visible: seven bioenergetic thresholds where your physiology actually shifts, not the single number the sport has been stuck on for twenty years.

What we built

Every layer required the one below it.

When Banister published the impulse-response model in 1975 and Coggan translated it into TSS, CTL, ATL, and TSB, they needed the same thing: certified data, a specific schema, and a new visualization to make it legible. That framework defined endurance training science for a generation. It has been largely stagnant since.

RaceProof is the next iteration. Three layers, each enabling the next.

01
Certified Data
Cross-source compilation and verification. Independent devices recording the same effort, resolved into a single authoritative record. When the data passes, it earns the badge.
Trust Score — Certified
02
Power Threshold Array
A new analytical model that replaces single-threshold FTP with seven bioenergetic transitions detected across the full power-duration curve. Each corresponds to a distinct energy system. Together they form a fingerprint that develops along fourteen independent dimensions.
03
Effort Signature + Loom
Every ride has a shape. RaceProof captures it as an Effort Signature: your effort rendered as color against PTA thresholds. Sprint power burns gold at the top. Threshold effort glows deep plum at the bottom. Line up a season of signatures and they become Loom, a biographical view of athletic development over time.

Introducing

Loom

Each vertical strip is one Effort Signature, the shape of a single ride. Color encodes the energy system. Brightness encodes fitness. A veil encodes fatigue. Line up a year of signatures and you see a season. Line up a career and you see who you are.

Research

The first population-scale evidence that racing develops the full curve.

Not at a single FTP threshold, but across every duration from 5 seconds to 20 minutes, for every rider in a validated four-year corpus. The data required certification. The analysis required PTA. The findings required Loom to present them.
