Raceproof

Raceproof analyzes your training and racing data through a model called the Power Threshold Array. PTA maps seven distinct physiological thresholds across two dimensions: power and time offset. Each threshold has a position that moves as your fitness changes. Together, the seven positions describe where you are as a competitive athlete, not as a single number, but as a shape.

Loom is the visualization that renders your training arc from this model. Every ride contributes to it. Over time, Loom shows not just what you did, but how your physiology responded.

None of this works without real training data from real athletes. That's what the beta is for.

If you want to understand the thinking behind the model, our research publication Torque is where we publish it. Start with The Racing Effect or Model Depth.

We're onboarding athletes one or two at a time, in order of registration. Sequential onboarding is how we build a research-grade product. Each new athlete gets our direct attention. We want to know what breaks, what reads wrong, and what we didn't anticipate.

You'll receive an invite when it's your turn. We don't have a date to give you. What we can tell you is that the queue is short and moving.

Here's what participation looks like:

• Connect Strava, Garmin, or upload your ride files directly (FIT or compressed FIT) when you're onboarded
• Race on Zwift at least a few times a month
• Tell us when something is wrong, confusing, or missing

If that's not where you are right now, hold your spot. The beta will still be here when it is.

Some of you are here because you're interested in this problem, not just the product. That interest has a place here.

Raceproof's analytical work is published in Torque, our research publication. If your data, your feedback, or your thinking materially shapes a finding, a feature, or a methodology, you'll be acknowledged by name in the work where it appears. The same way a researcher is credited on a paper they contributed to.

Everyone who completes a profile and participates in the beta will be listed permanently as a founding member of Raceproof. We take that seriously. Being there at the beginning of something real means something, and we want a record of who built this with us.

There's no commercial arrangement being offered here. What we're offering is credit where it's genuinely earned, and a permanent record that you were part of this from the start.

Before you complete your profile, we want you to understand what you're agreeing to. The full Beta Participation Agreement is the binding document, but here's what it says in plain language:

If any of this doesn't work for you, that's a legitimate choice. No follow-up, no pressure.
