In a hotel again

It seems I have been traveling quite a bit recently.   Anyway, did a little over 5 miles today on a treadmill set at 1% incline;  2 miles steady pace of 9:30 per mile, then quarter mile intervals ranging from 9:00 down to 8:00 pace (alternating with 2 minute recovery walks).  Finished up with a sprint of .10 miles at 5:00 minute pace (12 mph!).  So what was the purpose of all this?  Well interval training on a treadmill helps me with my pace awareness.  It also raises my lactate threshold.   The sprint at the end was liberating because I proved to myself that I still have a little speed left in my legs…
