Hi, Many thanks for any help in advance. I ran a 'personal' ie unorganised, just me doing a set route ultra distance last week- 14th July at my mum's in Spain. I ran 40.3 miles in 6 hours 46 minutes and 12 seconds. Problem was though, my garmin forerunner 410 (which is 3 years old) ran out of battery at 5 hours 30. Luckily I heard the beep and started the endomondo tracker on my phone straightaway so could combine the two 'seperate' runs on the site to show it was in fact one continuous run. Thus, I'm in the market for a watch that'll last the distance (excuse the pun). Obviously I'm looking at battery life so the two I'm looking at are the garmin fenix 3 and suunto ambit 3 run because of their battery lives. But they have lots of other functions like skiing etc so can anyone recommend a watch that is really just for running. I really liked my 410, but I need the extra hours battery life. Not too keen on huge watches. Top end range would be 300-400 quid. Any advice would be really appreciated.
