Thanks to Andrew for the informative explanation about the 375. Is this sort of knowledge in the public domain or are you "in the know" professionally?
Thanks to Corium for your clarification.
To build on Dave's point, a more pubby walk starts from the Beehive in New Mills, takes in the excellent Beer Shed in New Mills then continues along the Sett Valley trail ,via the Printers Arms at Thornsett before arriving in New Mills where you can take your pick from the George, Pack Horse , Royal Hotel or Dutsons. Ten past the hour up until 11 pm your 358 chariot awaits to bring you back to Marple. Three and a half miles and Four Good beer Guide ticks ( and a shoe in for next years guide for the Beer Shed ) - whats not to like?
