Ok I might have been blessed with glorious sunshine, but running through endless Swiss fields to the backdrop of the Alps and cows with bells was perfect.
Picture postcard stuff, with a short 5km though the city at the end, with the iconic water fountain for reference.
Well organised, Expo in the center of the city. It's Geneva, even enjoy a 5km to 6km run from the airport to the Expo!!
As with all things Swiss. Your Pound/Euro will not go far.... If anywhere. Just remember that and plan accordingly. :)
Life hax, land in Geneva and stay just on the French side close to the start. At least you might be able too afford to eat then in Euro land :).
Flat (for Switzerland) and a stunning looking marathon. Well recommended.
