I ran 11 miles this morning, although it was not all at once. I woke up later than planned, so I ran 6.5 miles initially in 50:46, with an average HR of about 138. After getting Anita ready for preschool and dropping her off at the bus stop I then ran another 4.5 miles in 35:02, with an average HR of 144. Total time for the run was 1:25:48.
I am really starting to wonder what is going on with the HR right now. When I first started wearing the HRM again my HR would average about 132-133 on easy runs just faster than 8:00 pace. Today, I averaged 144 bpm with a 7:47 average over the last 4.5 miles. I do not feel like the mileage is wearing me out right now, and I am pushing the pace only on rare occasions. Maybe it has to do with the change in weather (more wind, colder temps, etc). I probably just need to be patient and wait for the HR to drop back to normal on its own.
