Running

Only just realised:

I run 5 km 4 days a week
4d * 52wk = 216 days.
216d * 5 = 1080km per year (if I manage to keep it up this time (no sniggering you with a lewd mind (aimed at anyone who was with me and Kanga at SODs last night)))

Thats a lot of running but....

1km = approx 180 calories
1080km * 180 = 194400 calories

Or

1 Spicy Mos Cheese Burger = approx 400 calories
194400 / 400 = 486 Spicy Mos Cheese Burgers worth of running per annum!!!
