I love mashups and this one is defintely my current favorite!
They’ve equipped 5 of the riders in the race with a GPS tracker, heart monitor, bicycle computer and a radio that continuously transmits readings to the sportsdirector car which then relays the information to some server somewhere. The data is then overlayed a Google Map.
I absolutely love computers!!!!!!!!!!!!
