Hi, thanks for feedback!
So, if I understand you correctly, day 5 will be 1h15min slightly hilly route. In the second weekend there is a 5k@race speed and 1h easy run. Replace the 5k one?
Did the 6x1k today on a flat gravel path. Aimed at 4:35 with 80 sec rest. Usually did these sessions at threadmill with 1 degree incline, found it easy to keep the correct speed.
Did not use a heart rate monitor today, it's still in a box after we moved last summer. I guess I should do an effort and try to find it
