So, this is why I like Internet community. It helps me to understand all pros and cons of my work. I found an online coach!!! Absolutely Ready to work! Meet my Coach - Mr. Andrew!
All experiments with repeats and fartlek runs are in the past.. and in the future. Not now. We're working on Base Aerobic training. Although I made this morning 5 miles running on the streets (! never did it before) and in local "EthnoPark" I will start "90 min easy" with HR 140 - 145 beats per minute, tonight.
So it goes.
