rock solid heart rate
I was blessed with a much cooler day for my run today (even the weatherman was surprised).
And the heart rate based training (in the heat!) is obviously paying off because I was pleasantly surprised with today’s run.
Target Heart Rate: Up to 155
Average Heart Rate: 153
Distance: 10.7 miles
Time: 91:50
Pace: 8:35 min/mile
While I’m happy about the relatively low heart rate for that pace, I’m even more happy about how even it was throughout the run:
1st 30 minutes Avg HR: 150 (including the warmup mile)
2nd 30 minutes: Avg HR: 153
3rd 30 minutes Avg HR: 155
I ran all sections at a consistent pace so this shows that the old ticker is responding well to the training.
Feeling great!

Mark, thanks for sharing these data points. From the data collected, do you have an estimate for at what temperature you got to reduce your intensity in order to stay at target heart rate?
I am also curious to why you choose not to monitor your heart rate during a race. I would think that having collected HR metrics during training it would be valuable to monitor also during a race and adjust the intensity if you hit a HR that you know from collecting metrics previously means “trouble”.
I’d also think HR metrics from a race would add value when determining race strategy for future races?
