Ok, so I'm still overweight but have lost a few lbs, I still look like a beetroot but my recovery time is shorter, I still look at the ground when anyone is walking towards me but I am noticing the great outdoors more, and despite a wobbly nanosecond freak out when Laura said 'right, off you go' I did actually complete the session.
I've just seen R3 tho and am nervous for the first time about a run, but I know it's mind over matter so I'm just going to think how great I'll feel once I've done it and post my elation at such an achievement, just like all you graduates did.
