All riders will be given a SPOT Satellite GPS Messenger at check-in, which can be strapped to your bike or placed in your bag or back pocket. This device has a built-in GPS position that reports your position every 10 minutes via a satellite uplink. The position of all riders can be viewed at this website:
If you check out the website now, you can see my course checkout with 3 of the devices that I carried in my car. The website shows the last 50 or so positions at a time. You can scroll back and forth to earlier positions using the controls in the bottom left part of the screen.
This will allow friends, family and volunteers to follow your progress. The device also can be used to send a preset message to me if you need help and are out of cell phone range. More information is at this link:
