13:40. Last time 13:05 - BUT, my runs were about .32 miles vs. .25 so I ran about a quarter mile too far. I wish I could do this workout at the track but there's no where to do pullups.
I ran with the metronome set to two beats (one for each foot). It is much easier to stay with this way - thanks for the suggestion.
13.1 tomorrow - plan to run the first half hard and see if I can hang on after that.
