We are planning a west to east run from the Spanish border to this side of Nice. I am 67 - 5ft 5" - overweight but fittish (I pedal bike at least 15-25k twice a week - Pilates - swim - dog walk and ride horses). My bike is a Trek 7200. My husband thinks we will do 60miles a day - I have told him that is nonsense as I want to enjoy myself. I have a limited budget but would welcome suggestions - the Woosh Santana 3 or CD look good but is there anything else out there I need to look at please? Must be step through (total knee replacement) - we will need to carry panniers - and I want to be able to cycle unassisted wherever possible. Neither of us is particularly bike mechanic experienced.
