I was fortunate enough to visit the excellent Chelsea School Sports Science Faculty at Brighton University (where Hannah graduated from in 2006) and I was put through my paces by senior lecturer Gary Brickley. With increasing intensity on the treadmill, regular blood samples were taken from my thumb to measure lactate build up in my muscles. My heart rate was recorded and my carbon dioxide levels were measured in Douglas bags to calculate my metabolic rate. Initial feedback was positive (mercifully!!) and a full report will follow in due course. One conclusion is that I'll need an extra 2500 calories per day over the next 50 days!
