To the Marriott for stairclimbing. 8 climbs of 20 flights each (2 walking, 1 bounding, 2 running, 3 running+bounding), which replicates Tuesday's workout plus an extra running climb. My fastest climb was 1:34 -- not a PR, but that's okay since I'm not as fresh as I was Tuesday. HR data: avg. 76%/max 96%.
On a related note, I am getting pretty awesome at lip-synching to my iPod in the elevator mirror while riding from the 20th floor to the 2nd.
