Cyclocross race lap cards are a traditional way of hand scoring a cyclo-cross race. To hand score a race, print a dozen of these pages and simply hand write the bib numbers as the rider passes the start/finish. While one seated person fills out the lap cards, a second standing person should be dedicated to calling out numbers in the order they pass the finish line. Start a new card each time the leader approaches the start/finish line. Remember to bring a clipboard and pen!
In addition to lap cards, we recommend the excellent CrossMgr software from Edward Sitarski. This software provides complete support for cyclocross racing and produces outstanding results with lap times, speeds, GPS accurate mapping and integrated photo-finish pictures.
CrossMgr software can be used in either manual or automatic mode when used with RFID chips. In manual mode, bib numbers get entered on the laptop keyboard in real-time as the riders pass by. For most races, manual mode can be 100% effective, catching every bib on every lap.
For very wide finishes that permit groups of 7 or more racers to pass simultaneously, or when the finish speeds are very high, approaching 20mph, automatic counting using RFID chips is recommended.
Since CrossMgr has integrated support for J-chip RFID chip timing, racers can attach a small J-chip with Velcro to the head tube on their primary and spare (pit) bicycle. As they pass over the 40-foot wide rubber timing mat, their chip time and number is recorded with 1/100 second precision. The J-chip mat, receiver and chips can be rented from either the Buffalo Bicycling Club or J-Chip USA in New Jersey.
CrossMgr calculates and highlights with a green box the fastest lap in a race group. This allows a promoter to provide an extra reward to the rider with the fastest lap.
Whether you choose to hand-score your event or use CrossMgr in manual bib entry mode on a laptop, a separate person should be enlisted as a number caller. Ideally, the number caller is tall enough to see the numbers on the back of a rider, or stands on a platform. In addition, the number caller should turn the lap counter as the race leader approaches on each lap. The number caller can also ring the bell on the last lap.
