Same thought process as Cougie ... choose any car park in the New Forest and head off-path .... (actually most paths should be muddy enough)
Anniesophie - Yaktrax or similar ...unbelievably good for snow and ice. (and no, I don't work for them or sell them). Whether walking or running. Read the size guide and buy smaller than larger if in doubt - so they are a tight fit on the shoe.
