Running 6:00  0.75 mi (8:00 / mi)
Opening day of track practice. This year I get to coach the girls distance team, as well as the boys. Nice turnout - more than half of the boys and over a third of the girls are distance runners. I thought I would get some running in, but it couldn't really happen.
The kids did 2x800T on the track, 800m or 1600m T by "feel" around the fields, then 1-2 more 800T on the track.
Running 29:59  3.5 mi (8:34 / mi)
Decided to watch the Sabres game at the Penfield Y, which has individual TVs on many treadmills and ellipticals. Wasn't sure how long I'd make it, so I started easy to maximize possibilities.
This was during the first period; 1-0 Canadiens.
Avg HR based on a relatively small sample size, but my assumption is that it didn't change much at this pace.
Biking 14:00  3.6 mi (3:53 / mi)
Jumped on the bike between periods. Manual - started at level 8, but moved to 9, then 10 as my legs became able to spin. Did not get the HR above 120, despite this being much harder than the treadmill.
Elliptical 32:00  3.5 mi (9:09 / mi)
Moved to the elliptical (the kind where you use your arms, too) for the second period. The "big man" tied it at 1.
Kept enough effort up to keep the HR above 140 as much as possible. This also seemed easier than the biking.
