Every season there's a new way to go faster. A shoe, a powder, a protocol, a number your watch has suddenly decided you should care about. Some of it does something. A lot of it was never really tested, and the people selling it are in no rush to mention that. So we go and find out — including the times the answer is boring.
Everything on this site is one of three things: a promise put through the wringer, an explainer that makes you harder to fool, or a calculator that does something useful. No training plans, nothing about your knee — we're not your coach and definitely not your doctor.
"4% faster." "8 watts." "Recovered by morning." One promise at a time, held up against the actual research — with a straight answer at the end, including who gains and who's wasting money.
Browse the checks →How the engine actually works: VO2max, thresholds, fuelling, heat, why you slow down. Plain English, no jargon walls — the stuff that makes you harder to fool.
Start reading →Pace converter, race predictor, heart-rate zones, climb times for the famous cols, an aero lab. Free, no login — and every tool says out loud where it bends, because that's kind of our whole thing.
Open the tools →Carbon-plated shoes make you 4% faster.
It's done → read the full write-up: the numbers, the catch, and who gains nothing.
Endurance media runs on gear. Test shoes that never go back, affiliate links, launch embargoes, a long weekend in Girona. It's not that those writers are liars — it's that you can never quite tell where the opinion ends and the arrangement begins.
So there's no arrangement. If a shoe is a marginal gain dressed up as a revolution, saying so costs us nothing.
One vote, no account — your browser just remembers you've voted. Whatever wins moves to the front of the queue; the full list lives on the checks.
One thing at a time, dug into properly, reasoning out in the open. No schedule to keep up with, no filler. You can see what's in the queue right now.
