On "Staycation" this week...
Here's my HR record from a local 4.0 mile walk from June, then earlier this week I did the same circuit (4 miles) slightly faster.....
And the same circuit from last Sunday, and in slightly faster time overall...
The average HR has dropped from 129 to 119. After a flat start there's a couple of hills, the maximum HR is down and interestingly, on the recent walk my HR didn't cross above 120 until after the hill. In the June walk it was after 8 minutes (and on the initial flat bike path part!).
This seems good evidence showing that the fitness plan is working (loads of low-level cardio and strength training).
