The route rowed breaks down into three main stages:

• Westminster Bridge down the Thames, around North Foreland to Ramsgate
• From Ramsgate across the Channel to Le Havre
• From Le Havre up the Seine to Rouen where the Seine ceases to be tidal. Then continuing on through six locks to the Eiffel Tower in Paris.

Interestingly the distance from Westminster Bridge to Le Havre is about the same as from Le Havre to Paris, i.e. at Le Havre you are halfway there!
