After doing the R.F. L in July , I've been in trouble . I completed that grass run , 5k in 32 mins , then a week after got a park run personal best . But then it's all gone wrong , calf problem which the doctor said was a minor strain & nothing to worry about but it's not right & when I attempt a run it's bloody hard work I can't understand it my legs feel like lead every run & that's after I even rested it for 2 week . Did a steady 5k , then a 4k in 30 mins , coz a legs , then Sunday a meager 20 mins , sorry for moaning but it's getting me down I feel like I just can't run no more .
