During my W2R2 and W2R3 I was experiencing pains/aches with my pelvis which caused me to take a week break before starting W3R1. I found it hard to run during this week hence why I took the break, is it normal to experience theses pains. Take note I'm overweight currently so I'm a heavier runner.
I must also tell you that I may have been over doing it. Because I was walking to work and back 5 days a week this is a 30 min walk and was also going on walks during Sundays which could last between 4-6 hours around countrysides.
I also made sure I took the 1 day rest in between runs.
