The benefits of running with ID are as clear as day. Without one, if I become incapacitated, my family wouldn't be able to find me until they looked for me (which could honestly be a LONG time).
While carrying my driver's license around could be a solution, I learned that this comes with its own risks and inconveniences.
Enter RoadID. These guys have been advertising at nearly every race I've run, yet I thought it was something to worry about "later." But finally, for the sake of my peace of mind and safety, I got a Wrist Sport ID. See this sample:
RoadID sells a bunch of other products -- ankle IDs, shoe pouches, etc. I got a few promo codes with my order, so if you're out to save a buck, here they are:
