Read it. Study it. Race it.

Every Head of the Charles event, every year since 2012, sorted the way a coach reads it. The regatta's own times at Riverside, Weld, the CBC and the finish become a true breakdown of the race: where every crew stood at each gate, and who rowed the fastest piece between them, ranked. The weather at the start sits above the table.

Tap any crew for a result card: place, time and every gate, built for Instagram and saved or shared in a tap.

Look for the pink bows 16 ▸. That crew posted their GPS file. Tap it and you see the exact line the boat rowed, gate to gate, with the full analysis.

Drop the CSV or FIT file from your SpeedCoach or CoxBox and the app reads the race for you. It finds the real start line and the real finish line in the track itself: start the box early, stop it late, and the app does the rest.

See the line you steered, metre by metre, and compare it with any other crew's line, across every event: open theirs, open yours, and learn where they were fast, where you were faster, and what the shortest line through each gate looks like. Coming soon: your line and the fastest line of the year on one image. A coxswain's dream, and a rower's and a coach's too.

• Your line on the satellite view, animated, synced with live time, metres, split and rate
• The time through every gate: nine on the Charles, not just the regatta's three
• Your fastest and slowest 500, and exactly where on the river they happened
• Every stroke coloured fast or slow against your own average
• Where your time sits against every boat in your event since 2012, year by year, with the weather
• Several files side by side in the Practice Lab, and a race card to download

Post your file and your bow turns pink on the results page, so anyone can open the line you rowed. Every line posted gives the next crew a real boat to compare against. The leaderboard ranks every posted line two ways, fastest overall and shortest line, and over time the shortest line through each gate becomes the reference everyone measures from. Nothing leaves your browser until you say so.
