2020-10-25 · A great review on what, in my eyes, looks to be a great ultra runners GPS watch without having to pay the high price for a Fenix 5. From a device perspective I have a Garmin swim for the pool, and Edge 500 for the bike and still rocking the Garmin 310XT for my ultras, ok so it dies after 16 hours but it lasts for most of my 50 – 60 miles
