How is a race timed?
Most Racing Underground events are timed using the AMB Chip System. Each participant will receive a small transponder (chip) attached to a soft, comfortable neoprene strap. You must fasten the strap to your ankle prior to the start of the event. The chip will automatically register your time as you finish each leg of the race, and when you cross the finish line. No chip means no times will be recorded. After crossing the finish line, you must return your timing chip or you will be charged the replacement cost. If you drop out of the event, you must be sure to stop by the finish line and return your chip. Participants will also receive a paper bib number that must be worn on the front of the shirt, or on a race belt, with the number visible on the front when entering/exiting transition. In select races, you may also receive a bike frame number which must be affixed to your bike frame prior to the start of the race.
