LONDON -- Victoria Pendleton will race in the semifinals of the women's individual sprint in a few minutes. Pendleton has already won one gold in these Games, in keirin.
Keirin, pronounced "kay-rin", is an eight-lap race. For the first five and a half laps, the riders are paced by a motorbike. The motorbike begins at a speed of 25 kilometers an hour and works up to 45kph before leaving the track with two and a half laps left. Then the riders sprint to the finish.
Pendleton was just announced to the crowd, to a rousing ovation. She is racing Germany's Kristina Vogel in this semifinal. She won her semi. I'm still trying to figure out exactly how it works.
