First Frost

The plan this morning was to get up well before dawn and do my 10 mile loop, this time adding a few speed intervals along the way.  Apparently I didn't get the message that it would be the first real fall day we've had.  The weather out was in the high 30's, plenty of frost on the ground and on rooftops ( can anyone explain to me how frost can form when its not even near freezing? on the roof?)
I snoozed for an extra hour (thankfully I have a late start day today) and dragged myself up so so I could head out around 7:30.  Rather than doing my big loop I went for a 5.0 mile quick run (5 miles per Google Maps).  I deliberately pushed myself hard most of the run and had a very strong finish.  My final time was 44:56, or 8:59 per mile.  My iPod still not exactly calibrated read it as a 4.81mi distance for a 9:20 pace.  I went into the iPod workout folder and changed the XML file to reflect the correct distance and pace.  I did not bother to change all the split times though so it will be a little off if you look carefully at the graph.
I think the calibration was wacky because I was running about :40 harder than I normally do, no doubt lengthening my stride a little and therefore running fewer steps and therefore making the Nike+ think I didn't run as far.
All in all a good run.  Now off to work, and later off to buy some winter running clothes.
