swehI started with a sprint (I think it peaked at around 18mph) for a few seconds (30ish, I guess) to get my pulse into the zone as fast as possible. Maybe not a good idea, since my legs ached as a result. But, despite the average being higher than normal for me, and for a slightly longer duration, my heart rate never went out of the zone.
6.5 miles, 47:03 (so 8.3mph), 141bpm, 46:35 in zone, 731 Kcals
