Just a question- why not use UltraTrac mode? I wouldn't think that you'd really need data once per second in an event that lasts more than 24 hours. Is it really necessary?
Well I made some assumptions about what I'll find when I cut the factory cable open, but here's a design that I think will work. At the very least it proves that Garmin or someone else could bring such a thing to market. I have another cable on order and when it comes in I'll cut it up and fit it into the cradle.
so did you made any further progress on this? i.e. disassembled one of the fenix5 charger cables? would be cool to see some image on how they might look like inside (in case you can open up at all without killing it )
I've had a problem with the 'new' charger cable just lately. (Otherwise I love it. It's non-oriented! I can plug it in one go instead of 3. Isn't it amazing that a plug that can go on in only one of two ways nonetheless takes 3 tries, but if it can go either way, it only takes one?) Anyway, twice recently I've taken the watch off the cable after charging overnight only to find it had turned itself off. After starting it, I saw it had only 4% charge. It probably started at 90% The first time, I inspected the cable and found one of the pins slightly depressed (and I don't mean it was sad for letting me down...) I cleaned it a bit with a non-conductor like a toothpick and got the pin, apparently spring-loaded, to come out level with the others and not 'stick' when I poke it in again. Since the second time, I've been careful to watch what happens when I plug in the cable. Does it buzz and show charging, and does the percent charge go up after a few minutes? Also I now take it off charge if it is 100% before I sleep. It only loses a few % overnight and if I have time I can top-up in the morning anyway. This is a bit sad, but I guess it's what I need to do to make sure I am not going to wake up on the morning of the marathon with a flat battery....
BTW, the 'recharge on the run' pattern is one I find interesting too, though maybe cumbersome. My longest run so far was only 11hrs, but if I tackle a miler, I'm sure it would be above 25 hrs.

if you don't have long/important runs the very next day you may consider not to fully charge your battery and try always stay between something like 20%-80% which could extend battery life.

if you get hooked on ultra running you distances might increase and battery life decrease that's why it makes lots of sense being able to recharge your watch while still being able to fully operate it.
