|My usual 8 km run course on the outskirts of Hondo.|
As for the run, with fatigue accumulated in my legs from a solid week of hard exercise, I did not expect anything great, but my Garmin Fenix3HR watch pushed me once again to exceed my expectations with its great 'Race an Activity' feature where you virtually race your own (or someone else's) previous performance, and the watch gives you a real-time progress data. It's amazing how well this psychology works, since I've exceeded my previous performance every time, and by quite a lot!
Here's a chart of some of my runs on this course, using data collected by the Fenix3:
Date Race Time Avg. Heart Rate Avg. Cadence Avg. Stride Length Calories
11/10 39:17 148 178 1.14 493
10/29 39:38 162 174 1.16 552
09/10 41:10 150 172 1.13 491
08/24 44:35 153 165 1.09 566
If we trust the data is accurate, we must conclude that my body is quickly becoming more efficient, and fatigue has little role in spite of the amount of exercise I am piling on. For example the 10/29 run had my heart rate absolutely maxed out, whereas this time a much more comfortable heart rate nevertheless resulted in a faster run, a faster cadence, and yet fewer calories spent. Actually, it's quite comparable to the 9/10 run except for the nearly 2 minutes of time saved!
