What information do I need as a runner: distance, time / km, your heart rate and comprehensible analysis of the data. Since 2006 I run a Polar with shoe sensor and wanted something new and simpler. Long considered and then opted for TomTom. Great GPS clock, simple operation via 1 button control, good evaluation via TomTom my sport. The clock is reduced to the essentials, but I do not need more information in order to optimally train according to a predetermined training plan and the training then auszuwerten.Die clock looks great, very comfortable to wear, good and fast evaluation of training via USB interface, very good Kartenmaterial- by which I can review your run. Very important to me, because I also like (professional reasons) in other cities and countries to train, but also like new routes ausprobiere.Motivation by programmable training objectives. I recommend gladly.
