Olympia Rd walk today -- I didn't want to push it because I had a short night last night, but pushed it anyway, trying to keep the cadence up. I didn't have to fall off my cadence on the long uphill, but it was tough. Times 4:41, 5:00, 5:48, 8:31 for a total of 23:59. While not PB, it's second, by only 6 seconds, to the current best on 4/30/15.
I counted paces: 310, 650, 1050, 1742. That corresponds to average step rates (per 10 seconds) of 22, 23, 23, and 27 (!?). More cadence measurements are clearly needed :-)
