INSIDE MOBILE: The Marathon-One of the Largest Mobile RFID Applications
Applications for Mobile RFID include warehouse inventory management, but in an exciting new trend, Mobile RFID technology is now being applied to race result management in large running events such as 10K runs and marathons. Knowledge Center mobile and wireless analyst J. Gerry Purdy discusses how Mobile RFID technology is solving race organizers' biggest headache: accurately recording the finishing times for thousands of runners in races.You might think that running a 26.2-mile marathon is about the most difficult human activity. It isn't. Rather, it's keeping track of the places and times for 30,000 or more people that are running (and walking) in the race. I have fortunately run three marathons in my life, with the best one being the Los Angeles Western Hemisphere Marathon on Dec. 10, 1967. This is when I ran 3:23:00 or about 7:45 minutes per mile for 26 miles. Keeping track of the few thousand crazy runners that day was a nightmare. The race organizers had a long "chute" at the end of the race to hold hundreds of runners in their order of finish. Volunteers would tear off a small strip on their race number that included a duplication of the runner's race ID. The volunteers used a long string with a thick needle to thread each runner's small ID number through a small hole. This allowed them to capture the order of the finish of (almost) everyone.
Recording the time of every runner was much more challenging. It was impossible to have volunteers (even if there were a lot of them) record the time of every runner; there were simply too many runners finishing at one time. Race organizers would, instead, record a runner's time every 5-10 seconds and write down the runner's number next to their time. Then, the race officials would sit down and go through the long string of runner ID tags and interpolate times for all the runners, based on the ones for which they had recorded a time. This took many hours and the whole process was subject to error. That was 1967.
