Canardly, you'd be welcome to join
CTC Cambridge when we head out your way (which is about once a month). We announce on our runs lists where we'll be stopping for morning coffee, lunch, and tea, so you could ride out to join us at coffee, ride with us to lunch and then head home when we head back to Cambridge. For example, from the
October rides list, on Sunday 16th we're having coffee at Woodhurst (c. 11:00), lunch at West Perry (c. 13:00), and tea at Caxton (16:30), which ought to suit you.
