Sample Size Doubles

Paul, I have a sample size increase to your experiment involving footsteps per minute on an easy run. This morning Coach Blaise and I went for a 5 miler at 7:15 am before the regional cross country race. 20 minutes into it, we each counted our steps while the other timed for one minute. We ran along a river, so the course was perfectly flat on pavement. I may have been thinking too much about it, which may of course have skewed the data, but I also forced myself to run as close to normally as I would had I not been paying so much attention.

Data collection results:
Tim had 176 steps in the minute.
Blaise had 188 steps in the minute.

I found that by counting each planting of my right foot, the counting task was made easier. Then double the results.

  1. I ran with Simon this weekend, he was in the high 160s, like me. We were probably running around 7:30 pace (maybe even a little slower). Based on my very limited study (and some internet surfing), I am beginning to think that 160s-170s is pretty standard for an easy pace. Tim, how fast were you guys going? 188 is now the stride rate to beat...

  2. Just remember that Simon is the heel-strikin'est dude around. Probably not one to emulate for quick turnover!

  3. Oh, I'm guessing around 7:20-7:30 pace. We had literally just gotten out of bed, so it wasn't speedy. Blaise said he felt a little tight, so his cadence may have been high to compensate for tight muscles on a cold, early morning.
