Charlotte is 25. She's a Phd student from North London, researching the immune system at King's College; and in her spare time, doing lots and lots of riding.
Bob is 52, he's an energy consultant, and lives in the rolling hills of Chepstow, Monmouthshire. The riding is apparently fantastic there - plenty of sturdy climbs, stunning views, and reasonable drivers. Any rider's dream, really.
