The Timex Ironman series has found great success over the years and this is the latest iteration of the series that includes both GPS and Heart rate. Unlike many technical training watches, the Run Trainer 2.0 features an intuitive and easy-to-use interface so accessing your data and setting functions is a snap. The small profile tends to stay out of your way during efforts. The Run Trainer 2.0 is water resistant up to 50 meters so you will not have to worry about damage or corrosion from water. The watch highlights include vibrating pace, hydration alerts and interval timers. All data is easily downloaded with Timex's easy-sync for either PC or Mac and of course over to your TrainingPeaks account.
