Have finally bitten the bullet and joined a beginners group at my local running club. All ok up to this week when we've moved up to 3mins running - and now I feel like I've hit a wall - my back hurts when I run, my feet hurt and last night I just had to stop as I couldn't keep going ,cried and went home. Could kick myself but it just wasn't working. Not sure if it's the time of the day of the run (7.30 pm) or what I've eaten but when I do the homework run I go in the morning and struggle but last night even the first run of 90 seconds was hard going. Now I'm embarrassed to go back to the club - help!
