My old Garmin forerunner died and the stressful quest began to find the replacement. I like to have 1 GPS for running, biking, skiing, hiking and all things fun. Its primary purpose is for my long training runs and 100 mile trail runs and it has exceeded my expectations.
Being able to down load apps and set the display to something I like is fun, navigating the menu is simple and the buttons are easy to find even after no sleep for 24 hours.
While the Garmin doesn't have enough batter life to use the GPS for a full 100 miles (at least for most of us), you can charge it on the go using a Goal Zero Flip 10 recharger, you have the Garmin charger cord to deal with, but just for a couple of hours and then you are good to go for another 12-14 h. I'm not one that likes or needs to be connected to my phone 24/7, however, I have to admit that being able to run or mtn bike with my phone in my pack and receive text messages and see who is calling without having to stop, this has turned into a value added feature. While this was purchased for use with activities, I have found myself wearing this everyday since it reminds me when I have been sitting too long at my desk with a message to 'MOVE', I can't argue with that!
