it's been a month since I tested this watch for the time I did that in open ground. - The satellite search is a bit long 30 seconds to 1 minute. - I ran with others with a garmin accuracy of speed and distance is equivalent - The polar site is very good and easy to use to import or export the data: we have access to the course, altitude at the speed in km / h or tps per km is very motivating to see his career with this data and see the evolution of its performance. it comes without the HRM (this is normal given the price) but I think it's better to buy it because it has access to more settings allowing for better planning of workouts. So much for the moment I can say I hope it will help you, good races
