How about meet at 8.30. I could ride from home and meet you at the top of the reservoir, this would give you a start of about 8.15 from the car-park and with a 2 hour ride we would both be back at Ticknall for 10.15 ish, plenty of time for coffee and a cake from the Post Office and for you to get home in good time . I'd ride home via the way you set off.
