After doing W3R3 successfully on Friday, last night I noticed a bit of pain in my hip near the front when I was getting up fro a seated position and also when I was climbing the stairs. This morning I did W4R1 without any problems during the run but now the pain is sometimes also present in my groin, especially when I am extending my leg (e.g. pressing the clutch in my car). I don't really want to make any excuses not to run as it doesn't hurt at all when running or walking but nor do I want to make it any worse. The pain, when it's there, is only brief and quite sharp. Do I rest it for a while and put C25K on hold or carry on?
