I just bought myself a Garmin Foot Pod a few days ago. Today is the first time I used it for my run. I used it in my weekly long run (last ~2hours or 18km) with phone's metronome on, and set at 180 beats per minute.
After the run, I looked at the run cadence data and found several interesting findings:-
1. For the first 20 mins, I was running at 182 spm.
2. Eventually, my run cadence dropped to 180 spm.
3. When I tried to speed up for 2 mins right after 1 hour of running, my run cadence further dropped to 176 spm.
4. When I ran back at my original targeted speed of ~6:45 min/km, my run cadence increased back to 178 spm.
5. The run cadence of 178 spm only last for another 20 mins before it dropped back to 176 spm.
6. At close to 2 hour of run, I again increased my speed. This time, my run cadence increased back to 178 spm for only around 5 mins before it dropped back to 176 spm.
7. At the end my long run, where I was getting real tired, my run cadence varied from 176 spm to even 172 spm.
From the data, two areas that I need to focus on in order to maintain my run cadence of 180 spm, ie. when I increases my speed and when I get tired. Apparently, I didn't respond well with my phone's metronome. Or, I could be even worse without the metronome on. I will try out one day to find out.
