The 26.2 with Donna Dede Marathon was streamed LIVE on a webcast so it was thrilling to watch and listen as my sweetheart began a 1/2 Marathon on Jacksonville Beach.
Also thrilling that I could track her progress as the athletes were wearing RFID chipped ankle bracelets. When the race was started they ran across an RFID wire stretched over the road. The wire powers the device with a high frequency signal picked up at the antenna which transponds its unique serial number. Everyone’s time is tracked by running past the wire. At strategic choke points they passed a different wire which marked time. Using T and D formulae one can derive ET, Pace, and ETA statistics. I’m streaming tears and cheers of joy for her!
