W4R1 was tough for me. I was not able to get a comfortable stride. I was on the verge of giving up on the first 5 minute run. However, I managed to push on and complete it. Do others have a similar problem where you struggle with your stride on some days?
Would a longer warmup help? Last week I was able to complete a 9 minute run after the WK3 run.
Also on rest days, not while running, I feel mild pain on my knees when suddenly standing up etc. Almost as if my knees are hardening up. I am a 42 year, out of shape(BMI 31) man. Is this knee pain something to be worried about?
