3 x 500m UPDATED - correction

UPDATE:  These times were too fast, didn't seem right. I actually ran a 485m, not a 500m.  It was an improvement by a good margin over my last 500s, but not as much as I had hoped.  *I corrected the 500m times and added 2.5 sec to each interval time in the workout summary.  (From this particular starting line, I was supposed to run in lane 6 the whole way, but I cut to lane one for the 2nd turn, so my second "200" was really a 185m).

The day started out frigid, snowing hard with an inch on the ground, 30º... but by early afternoon, snow melted from the track and the temperature rose just above freezing.  There were still intermittent snow showers during my workout with temps in the 30ºs.  But that didn't stop me from getting a real good track workout, although too cold to run anything short and fast.

3 x 500m* - 82, 82, 83

*The first two 500s were almost identical, 63.5/16 splits for the 400m and last 100m.  I was amazed at the first one, that it didn't wipe me out.  So, after a good rest I ran my last one a little more aggressively, hitting the 400m in 62.5 and dragged the last 100m in a slow 18 sec.  Nevertheless, best set of 500s in memory.  Quite a bit different when I suffered severely running just 2 x 500 in 83, 87.5 only 2 weeks ago.  An improvement. 

So what has changed?  This, for one:
