I went to the park with my 4 year old daughter yesterday and we had a series of sprint races. Not only could I only just beat a 4 year old girl in a sprint, but my hammies are as tight as a drum this morning. I think they call it the dignity of ageing gracefully...I went for my first run in about 3 months yesterday, a bit over 4km in 20mins, lucky I have today off tho, because I'm finding it quite difficult to do anything that uses my quads
