Mrs Perdita Shrimpton loves beaches. And particularly running on them. When I take her to a beach she runs all the way to one end. And then turns around and runs all the way to the other end. This morning, at Maslin Beach, she took off as usual, and it was 1/2 hour before I next saw her, charging back and past me in the other direction.
She used to run for about 45 minutes before she was ready to be put on the lead and taken back to the car. Today, it was nearly an hour.
She runs at 20, maybe 30 mph. Not as fast as a greyhound at 40+ mph, but in the upper part of the doggy range, I’d say. So she puts in a fair few miles when she runs for an hour.
I do not try to keep up, of course, but generally stroll around and paddle in the shallows until she tires.
