I completed W5R3 on Dec 14 and then Covid hit me hard . Next three weeks I could not even think o f walking. cough and breathlessness. After three weeks , I had no idea on the level of fitness or my lung capacity. To test my capacity I ran w1r1, w3r1 and w5r1. It wasn't all that easy but was still doable.
Last week I have completed run 1 & 2 of week 6 . My Run 3 of week 6 is due today. I am not confident but give it a shot.
