started W4 tonight anf failed.I only manged 3 min followed by 3 min instead of 5. I then did 3 min followed by 3 min again. My calf muscles where aching me. I am not too sure if its related to the fact i went out running at about 7 pm and the last time I ate was at 12.30 pm(bowl of tomato soup).Even if it wasent the cause in my heart i know it wasent a good idea. should i do more stretches beforei start? I am going to remain positive. I have run more than in week three so there is an improvement .I will remain at week 4 until i achieve three consecutive runs up to laura's exacting standards. I am going to have something to eat now!
