Measuring the distance of the English Channel swim


The second in our series of video demonstrations of marathon swim route distance measurement in Google Maps tackles the most famous of all marathon swims: the English Channel. Despite its iconic status in the sport, nobody can seem to agree on what, precisely, is the route distance. CSA, CS&PF, MSF, and Wikipedia all have slightly different answers, though most seem to agree it’s about 20 or 21 miles.

Note: MSF and the LongSwims Database use 33km (20.5 statute miles), rounded up from 32.9 km – the straight-line distance between the eastern end of Shakespeare Beach and Cap Gris-Nez.
