The official website describes the March March March as “a long, flat, pointless walk across the Fens from the town of March to Cambridge, a distance of about thirty miles”. With a description like that I simply had to experience it. Except I did it in the reverse direction from Cambridge to March.
It certainly was long (33.9 miles) and very flat. And arguably quite pointless.
There was almost nothing of interest along that route except the end of the the Hundred Foot Drain, which I failed to get an adequate photo of.
