Paying Attention: Saturday’s Olympic schedule has the first round of Biathlon competition. Biathlon is a “fusion” sport–it combines cross country skiing with target shooting. The key is to move around the course quickly (which uses lots of energy and ramps up the heart rate) and then slow down your heart rate and nerves enough to do well in the shooting (the contestants use .22LR competition rifles) portion of the event. It is not easy. A complete and very short course in Biathlon, which has lots of variants in terms of distance and is a sport contested by both men and women–can be found in this wiki. Also, YouTube hosts a concise Official Olympic Video on Biathlon that will get you into the sport.
