Not an Olympic Event

Went for an urban stroll and a damn good gossip today with a friend.
Not sure whether you have to understand Yorkshire to follow this explanation of the passageway illustrated here:
In Sheffield's Sharrow there's an old gennel called 'Frog Walk' and many people assume that it was so named because of all the frogs which could be found there or close by. But no, I've been assured that the real reason was that there used to be the 'Old Walk' and Frog Walk was really the new walk. The Old Walk was 'T'owd Walk' and so the new walk had to be Frog Walk.
