By five in the morning it’s already running. Every horse declared to run that day, and behind each one a history: what its sire has done at that exact distance, how it’s gone on that ground, the mark it won off against the mark it carries today, which jockey and trainer have made it work together and how often. Thousands of records, read one at a time, before the country’s awake.

The majority of runners give us a reason to filter them out, and that’s exactly what we’re looking for. Every name that goes is one less place to look. What’s left has earned its place four different ways, and those are the RHR Angles. A handful of horses a day, out of hundreds, each one standing on evidence you can see for yourself.

The work’s already been done for you, and it’s all yours. If you just want the names, they’re on the homepage every morning. If you want to know why, open the Angles page and we’ll walk you through it, horse by horse, right down to the record that put it there.

But finding the shortlist is only half the job. We need to know whether it works.

So before racing starts, the prices of every horse on our shortlist set us a target. Together, they tell us how many winners the market expects that shortlist to produce.

We call it Expected Winners (xW).

Football has xG. RHR has xW.

That gives us something most racing selections never have: a benchmark fixed before the result is known. If the Angles produce more winners than xW, we’ve beaten expectation. If they don’t, the numbers say so. The target doesn’t move afterwards.

Every day since we started has taught us something. The Angles are sharper for it and they’ll be sharper again a year from now, because that’s what happens when you keep measuring what you do.

We’re not here to shout at you. We’re here to show you what we found, explain how we found it, set the bar before racing starts and show you whether we beat it.
