Objective: VO2 improvement - warm up + 6 x (4 min hard, 4 min jog) + cool down miles Conditions at 5:00 AM: 31F, light wind (2-10 mph), snowing lightly. Pavement went from bare and dry to white within 1st 4 miles, then snow stopped falling. I'm just guessing at the number of VO2 miles. I went by time and by effort level but I think I was pretty slow for a VO2 session due to the snow and the tiredness. Nevertheless, I feel really happy with this workout because I pushed myself.
There is an interesting discussion about cadence on the Running Times marathon forum. Lots of points of view & lots of things to mull over + some links to drills videos but I haven't watched them yet.
