Hi I'm a very very new runner. I'm 57 and haven't run since my earlier 30s and that was on a treadmill! I've taken on the couch to 5k challenge as I'm overweight and need to get my blood pressure down. I've been out for the third time today but boy do I need help. My feet hurt every time I stand up, I've pulled the muscles on my inner thigh and to cap it all I tripped today and took the skin off my hands! I completed the session anyway which for me is quite an achievement but am I overdoing it, are my shoes wrong? Do I need to rest till my pulled muscles recover or do I just soldier on? Or is this just normal!?
