Route on Mapometer with height and gradient graphs and alternate download options.
Final section in Rennes is not as described in the route notes because I couldn't follow them on Streetview.
The above should be used in conjunction with the route notes which contain important additional information. It has not been checked by the organising committee. Apologies in advance for errors.
GPS Visualizer can convert to alternate formats.
Note there is an error in the route notes at 7.7 miles; they should say "Turn left onto the D275 Rue de Bois Martin".
