In which a man who has called handicap racing a conspiracy for twenty years is forced to write the maths himself.
There is a specific tone of voice masters rowers use in a boat park when they have just lost to a pensioner. It is the tone of a man explaining that the tide was against him, except the tide, in this case, is called “age grading,” and he has quietly decided it is a conspiracy.
I have used that tone myself. More than once. At a regatta some years back I watched a 68-year-old single sculler post a handicapped time that beat a crew half his age, according to the results sheet, by 4.2 seconds. My first reaction, delivered loudly enough for several people nearby to overhear, was that this was not a result. This was an apology wearing a stopwatch.
Handicap racing, as far as I was concerned, existed to let older rowers feel competitive without doing the inconvenient work of actually being fast. Real speed was the number on the clock. Everything else was a participation trophy with a decimal point.
That opinion survived, largely unchallenged, for the better part of two decades. It survived because I never had to build the thing myself.
Then a member emailed asking for help settling a club regatta with a proper mixed field — four boat classes, ages spread from mid-thirties to early seventies — and a genuine need to know who should start when. Most existing tools handle two boats at 1000 metres and call it a day. Nothing compared a whole field at once. Nothing handled a head-race distance. Nothing produced an actual start sheet you could hand to a race officer.
So I went looking at what World Rowing itself publishes, expecting to find the sporting equivalent of a participation trophy factory. What I found instead was a decade of Masters Regatta results — thousands of them, across every boat class and age band — fitted to an age-decline curve for each one. Not a flat percentage knocked off for being old. A boat-class-specific model of how fast a human being of a given age can reasonably be expected to move a boat, built from actual racing.
I did the thing I do whenever I discover I have been confidently wrong about something for twenty years, which is get faintly annoyed about it and then build the tool anyway. Partly because the member still needed one. Partly, I will admit, because I wanted to see what my own numbers looked like against the curve, and there is no faster way to find that out than writing the code yourself at eleven at night.
The curve does not care about my feelings on the matter. It also turns out “real speed” was never really the argument. The argument was that I did not enjoy being told, mathematically, exactly how much of it I have lost.
Here is what is live now. Build a field of boats — any mix of gender, boat class, and age category or exact age — and get a prognostic finish time for each one, at any distance, including presets for the Head of the Charles and the Silver Skiff. It gives you the handicap gaps between boats, builds a pursuit-style start sheet with real stagger times, and lets you enter actual results afterward to see who genuinely outperformed their number on the day. It is free, open to anyone, and built to be reused every event rather than admired once and forgotten.
The calculator, mid-comparison — prognostic times and handicap gaps for a two-boat field.
I still do not entirely enjoy what it tells me about my own splits. But I have stopped calling it a conspiracy at the bar, which for me counts as significant personal growth.
It lives next to this year’s training plans, for anyone who would rather know the number than argue about it.
There are a couple of other quietly useful tools in the member library too — a heart rate zone calculator and an aerobic power tracker. More on those shortly, but they’re already live if you’re a member and impatient.
