Greg is a team player, having been a keen oarsman and sculler for decades. He remains competitive albeit he rows and sculls more slowly than he once did, and is Chairman of York City Rowing Club.

To get away from all things work-related, he goes tall-ship sailing.

In such spare time as he has, he enjoys opera, travel and, of course, his family.
