Today I'm making my yoga debut. I am booked into a beginner's Hot Power Yoga session and I'm pretty much terrified - and that coming from a person who wont even bat an eyelid about doing one of the legs of the Ride London relay race without ever having done a cycle race. You see, I'm inflexible. Stiff. Yoga requires supple limbs, patience and spatial awareness, of which I have none. So yeah, I'm terrified but also oddly excited....there's just nothing like a good challenge!
