I have gave myself 3 rest days as my legs were stiff and achy before I started week 9. I did it but I never thought adding just 2 teeny minutes onto the 28 last week would be such hard work. Do people find their legs get less achy as time goes on as they get stronger? The last few runs have really affected my legs. Do you think I should get a gait analysis and would this help improve the aches and pains?
