i have a new device to bore you with. not a drill (that would bore you in a more literal sense). no. i have a pedometer to so i can see how far i walk.

and so we learn that from my home door to my office door is 4.976 km (3 miles) and i walked at 5.34 km/hr (3.3 mph).

52 minutes of my journey this morning was spent walking and i took 6144 steps. (this obviously excludes the 50 minute train journey and time waiting for the train to turn up). Oh, and i may have burnt 232 Kcal, but i don't know what that means (i need a measure in Mars Bars)

This is a walk i do twice a day. my new boots are still giving me blisters

but what about the science of walking speed ? try here.
