Anybody taken their watch for a day long hike? Let's say you have the Outdoor Walk activity on the whole time during the walk, how long can the battery last?
I'd guess five hours (if that's the rated time for a full run down) since the GPS is on for outdoor walking too I think.
If it's like the first one there should also be a power save option, which turns off the heart rate monitoring, completely I think. I used it when I was training for a marathon where the practice runs were getting long and killing the battery, and I don't think it took any readings at all, not even the regular 10 minute intervals. I wish there was some more compromise with that setting. Otherwise there's another future revision wish, continuous HR monitoring throughout the day.
One of these days I'll run a marathon. I'll probably die immediately following it
Maybe I should watch Run Fat Boy Run again for inspiration
Go for it! I ran LA this year as my first one* after never really being a runner at all my whole life, it was pretty cool. I signed up with a charity team and they had a training plan...which I didn't really follow except for Saturday runs with a group, but ended up ok, if slow (albeit faster than most of my friends). Run walk pacing (run x minutes, walk y minutes) helps massively if you can't run continuously, and makes long distances totally doable.
*Possibly my last one. Pretty sure I
could do another one, it's just a matter of whether I want to go through the long training runs again in preparation...and the last few miles of the marathon itself. Like I felt great at the half marathon mark, and still felt fine at 18-20 miles. After that the course got really boring and it became a slog until the finishing stretch. I'm totally down for half marathons whenever, I'd probably be fine with a 3/4 marathon if that was a thing, but those last few miles are what make me question ever wanting to do a full again.
I will say one neat thing about the training, at one point I added the numbers up and noticed I broke 100 miles. That's nothing for a regular runner, but for someone that never ran it was pretty cool.
