Cadence Training View

When editing the “Sport profile,” you can delete and add new “Training Views” on your Polar watch. There’s not much elevation in Florida, so I deleted that training view. Since I purchased a Polar Stride Sensor, I added a training view that shows average and current running cadence.

7 Mile Training Run

I ZoneLock my Polar Vantage M watch in heart rate zone 3. Then I change the training view to cadence. I increase my cadence and my watch vibrates. Changing the view back to heart rate, I have entered zone 4. To keep my heart rate inside zone 3, I reduce my cadence.

My first three miles I ZoneLock in HR zone 3. At mile two, I drink 8 ounces of G-endurance. Then at mile 3, I take HUMA energy gel with 50 mg of caffeine and start interval training.

After resting for three minutes, I increase my heart rate and ZoneLock in HR zone 4 for the next 7 minutes. Then my watch vibrates at mile 4. I unlock zone 4, slow down, and drink another 8 ounces of G-endurance.

I repeat this process for miles 5, 6, and 7. Looking at the Polar Flow session analysis, I discover my pace increases when I lengthen my stride while keeping the same cadence.
