Well, after 3 rest days due to family commitments I thought this would be tough, it was! But not as bad as I thought. Seem to find my thoughts drifting while running, away from focusing on my legs, lungs or heart etc which is great as before you know it Laura's telling me to walk! Looking at W4 I admit looks a bit daunting. I Don't feel ready but I've said that before now!
Some intervals my lungs cry for help and other times my legs are giving out before my lungs...... No consistency here
