On the blog entry referred to above ... I have updated the GPS file to include a route from Charles de Gaulle airport to the Bastille and vice versa.. The route is based on David May's website, here:
Bicycle from CDG Airport to Paris or vice-versa
Possibly of use to riders who are staying on after PBP to do some tourism and who might be using an airport hotel.
There is also a small bug-fix to the planning spreadsheet. You can either download it again or modify the PBP15 page so that cell CA2 contains the formula +CA5. Improvements to power-to-weight ratio were being double-counted with changes to total rider+luggage weight.
