Good thread subject.
For me it is more about the sense of adventure and achievement of getting into wild places, rather than distance covered - a mile on the hill can be as tough as 2 or in some cases 3 on the flat. Taking over an hour to walk the mile and a bit from Kentmere Pike to Harter Fell in full on winter conditions earlier this year springs to mind - utterly exhausting but intensely satisfying. A taste of winter on the fells -
VIDEOI qualify on 2 (we have a
cupboard full of sleeping bags and mats), and 3 (just because I can do mental arithmetic easily - I'm the same with pounds and kilograms for cooking) but although I record mileages, I'm really not that bothered whether a walk is 9.8 or 10 miles, or 5 or 5.2 miles, I just round it to the nearest mile, and sometimes I just guestimate.
My list:1: when you start thinking about possible new routes whilst lying in bed at night
2: when you have a cupboard full of walking gear, and it spills over into the garage (same as Dave's 2).
3: when your partner starts grumbling about the amount of gear that you have - "Do you really need that 4th tent/rucksack/whatever?"
4: when holidays have to have a walking related element to them.
5: when you squeeze in a walk on business trips or family visits.
