Congratulations to Nathan Blake of Oxfordshire. He was first out of the curiously pixellated hat with the correct answer to the last Torq Teaser - the measure of how fast a food raises blood sugar is called the glycaemic index. Torq's Matt Hart explains: "Understanding the speed at which different carbohydrate foods raise blood sugar is extremely important to the athlete. A high glycaemic index (GI) carbohydrate shortly before exercise could actually drop your energy levels like a stone just before you start your ride. Similarly, a low GI carbohydrate during exercise may not get into your bloodstream quick enough to have a significant effect. More information is available at the following link: http://www.torq.ltd.uk/pfm_disp.asp?newsid=14."

There's a new question up now, and another big box of tasty Torq bars up for grabs. Head on over to the competition page and chance your arm...
