No one said it would be easy finding gifts for athletes intent on the most esoteric new derailleur or running socks. But this year it's easy: Consider the Polar CS300 Cycling Computer for the triathlete or weekend warrior. This computer can be mounted to a wrist or a computer, so users can go straight from run to ride. The unit calculates heart rate, distance, speed, estimated time of arrival, and calorie consumption, and the OwnZone feature can also help design workouts based on the variability in your heart rate.
