If you’ve read my blog before, advance warning: this is a different post from my usual ramblings on the highs and lows of running. And it may get a bit ranty. Sorry.

It was inspired by this recent article in the Washington Post by Dr. Aseem Malhotra. Those with good memories may recognise Dr. Malhotra’s name as one of three cardiologists who were all over the news last month after writing in the British Journal of Sports Medicine that activity isn’t part of the solution to obesity.
