Drop the CSV off your SpeedCoach or CoxBox. That is all there is. You get your time and your distance from the real start line to the real finish line, then every stroke of the race goes back on the river so you can see where the metres went.
For your own curiosity and your crew's. Nothing here changes, challenges or replaces an official result; the regatta's clock and the regatta's umpires are the record.
No file handy? Try a real U17 4+ from the 2025 Head of the Charles.
Everything in the results is public already: your event, your bow number, your time. The one thing nobody has ever been able to see is the line you steered. Add it, and your race sits on the river next to every other boat in your event and your discipline, for anyone who rowed it, coached it, or lost to it. Labelled by year, event and bow only. Pull it any time with one click. Old files welcome: 2024 and 2025 go in under their own year.
Your line coloured by split. The dotted line is the reference, the best track we hold for this course. Press play.
Split and rate against distance, each a ten-stroke average, with the gates. Hover to move the boat.
From start is how far into the course each gate sits; the leg is the stretch from the previous gate to it. Orange is metres you rowed on that leg that the reference line didn't; green is metres you saved. Click a bridge to fly to it and see which arch you took.

The page knows where the Head of the Charles start line and finish line are. It reads the GPS track in your file, finds the moment your boat crosses each line, and times and measures the race between them. The button on the box does not matter. For the cleanest result, start the CoxBox or SpeedCoach well before the start line and stop it after you are through the finish; if the box was started late or stopped early, the page estimates the missing few metres at your own speed and says so in the notes. The gates are calibrated against official race times to within half a second. This is for interest and training only: it is not official timing and it does not overrule, dispute or replace any result published by the regatta.
