With both boys in the double stroller. Peter ran some laps around the playground when we made a pit stop for a Jeffrey to play and then some more at the Harvard track. Peter ran 1 full mile. On the track he ran an 800 with 400 splits of 3:52 and 3:45. He also ran a 100 in 40 seconds. Definitely the farthest he's gone. He seemed happy with his accomplishment. I love mornings like this.
