Based on a standard leg of 100 miles (clearly this depends on form of transport and terrain - I’m using the widely recognized Ford Focus on single-carriageway A-roads) and a Biblical stint of 7 years (Exodus 21) then a leg per stint is 4.4 furlongs per fortnight.

I once set an entrance exam question about snails moving at so many furlongs per fortnight. It didn't prove popular.
(I did define a furlong very carefully...)
