Iain and I ride to Princes Risborough for the start of Keith's ride With electrical assistance, Keith sets a cracking pace until he realises no-one is keeping up. Along the Phoenix Trail to Thame and beyond, we stop at Waterperry Gardens for elevenses. The wasps are very friendly, which is just as well. Due to the heat Keith chooses an abbreviated route, which doesn't take in the mountainous climb to Brill that he normally takes. Soon we are back on the Phoenix trail with a brief diversion to the Three Horseshoes at Towersey for lunch. First time I've encountered a roast beef baguette with gravy. Back at Risborough, Iain and I say farewell to our companions, and head up the Chiltern Escarpment. Past Gt Missenden, then a climb up Frith Hill, we stop at Masterchef Amersham shortly before closing time. My GPS doesn't want to wake up, so the last 18 miles of my ride is not recorded. You'll have to take my word for it that 70.4 miles is actually 88.2.
