thanks re: newborn! actually most thanks to my wife, who is very encouraging about keeping up training despite herself still not being healed enough to do anything more challenging than a couple of walks per day and some light core work. i did finally skip a day yesterday because the lack of sleep caught up with me and i felt drowsy all day.
and yeah i'm doing the intervals mostly on a track; on a ~1.3 km loop when the track's closed. it's fine, i'm not expecting them to be mentally stimulating. just whining, lol.
