Head of the Charles — Best Line Leaderboard

Upload your race .fit file. We measure how closely you held the ideal racing line. Fewest extra metres wins.

Your boat GPS records the line you rowed. The best line is the shortest legal path through the bridges — the theoretical minimum. % over best line is how much farther you rowed than that minimum.

No need to trim your file — automatic gate detection finds the race start and finish, so upload your whole activity (warm-up, race and paddle home).

Ranked by how close to the best line — lower % is better. 🥇 🥈 🥉 mark first, second and third.
