Hey Jake, the Garmin 101 looks like the ticket. I used the Garmin etrex in last year's OBX and had trouble reading the screen. It survived the trip - I still use - but I'd go with the 101 or 102 because of the wearability and the countdown timer. Good luck this year, I wish I was doing the race, but maybe John and I will hook up for next year's Tybee.
