The runner tomtom is my first GPS watch. I made the purchase after having long hesitated between different models and to this day I do not regret my purchase. It is very easy to use, acquires satellites quickly and finally allows me to have various information related to my outputs (distance, speed, altitude), in short, is a very good tool. It is not perfect. I wish we had the speed in km / h but you get used pretty quickly to the time / km. Autonomy also seems a little shorter than the scheduled 10am and especially the total load is long. I have not found either auto pause at the stop of the race. But these few annoyances do not spoil my pleasure. It corresponds perfectly to my expectations and more powerful models are also much more expensive. A final advantage. Its look is very nice and it's very light. The reading of information is very easy and fast.
