140 bpm is number I´m trying to reach on my easy runs. So far, it has been always above it, normally between 145 and 150. It´s no big deal, but it would be a great sign of improvement if I could run at current pace and reach 140bpm as average.
After 39 days (30 runs) running in the morning, I ran last night. Result: 141bpm at easy pace. Ok, it was only one run, but this is what I look for my morning runs.
Today my performance on morning runs has improved, I just can´t say if it´s as good as on night runs. I have a 10k race 30 days from today. Then we´ll see.
