Well managed to get out on my bike tonight and managed more than I thought. I gave it a good 45 minutes around the village and through the forest and I was absolutely exhausted by the time I got home.
I have to admit I am feeling it a bit now, have felt a little lightheaded since i got back, I have had my shake and a bar since i have been back and I think I will take it a bit easier next time.
I dont want my new found ability to exercise to back fire on me.!!
