This past weekend, it was really cold in Oklahoma. With flurries blowing, I had three choices: take my walk outside and be miserable, skip my walk entirely, or go with my wife to the rec center and walk as she swam. I opted to go to the rec center.
We have an “old folks” rec center near our home. If you are over 50, you can join and take advantage of the programs specifically designed for more seasoned citizens. While I don’t physically put myself in this age group, I can’t hide from the chronological facts. So, as she swam, I took my first walk on the 11-laps-per-mile track.
When I first started, the track was not crowded. As I added laps to my total, more people came to join me, and I was glad to see people doing healthy things. But, I had some criticism. If people want to walk 3 -across and take up the whole track, I consider this rude. When I walk outside, I stay aware of who is coming toward me and who is behind me. On the rec center track, I had to get in the habit of yelling, “On your left” while a few yards behind. (Also, good etiquette outside.) They moved with slight annoyance. I thanked them for allowing me by…or was I thanking them for sharing the track like a civilized person would do? While this was annoying, I had a far greater frustration.
Typically, I walk 15-16 minute miles. I have gotten in the habit of using a phone app that announces the miles and the minutes per mile. When the app told me I had completed my first mile at a time of 19+ minutes. I was appalled. Prior to this disturbing announcement, I was convinced I was walking an average pace. Yes, passing people and diving through gaps does cause me to break from my normal stride. Yet, walking 3 minutes slower than normal did not sit well. The only way to solve this problem was walking faster. When the 3 miles were completed, I did not greatly improve my minutes/mile speed.
After doubting my masculinity and almost accepting the fact I am old, I developed a theory. I am certain my phone app and the GPS function were actively working against me. The GPS was not able to detect whether I was on the outer ring or the inner walking ring.
My extremely well-read friend gave this response to my question:
Walking small, repetitive laps (e.g., around a track or small park) can sometimes confuse GPS systems. The curves and overlapping paths may result in under- or over-estimating distances due to signal "drift" or smoothing.
Whether this is accurate or not, I am claiming it. As long as I am in control of my faculties, I will not trust a sporadic electronic hiccup over my gut. And, by extension, I am unlikely to walk rec center laps again…
