A group of us are going from London down to Portsmouth at the end of the month to go over to the Isle of Wight Randonnee. We don't necessarily want to ride the full London-Portsmouth distance on top of the Randonnee itself so we're thinking of getting a train part way.
Does anyone have any recommendations for a quiet route from e.g. Guildford, Haslemere or Horsham down to Portsmouth? Cheers in advance.
