Get Lost :)
A friend of mine is a ~30 hour 100 miler, and since there are no running GPS units that last that long, she wears her first Garmin 305 on her wrist and keeps another 305 in a drop bag roughly halfway through the race. Does anyone else do this during a 100?
I guess the sweet spot will be a GPS that truly lasts 24 hours. I think the 310xt is supposed to be a 20 hour watch. Mine lasted for a full 17 hours straight, so I was pretty pleased with that.

I'm running somewhere tomorrow. It's going to be beautiful. I can't wait.

Even if the battery lasts 12 hours, the Forerunner doesn't have enough memory to store every bit of detail. The truncation of data starts at around 4 hours, I believe.
I'm not sure how correct this is, but I know that all my HR, pace, and GPS data were fine for all my runs, irrespective of length.

I borrowed a buddy's 405 and it conked out at 6 hours. My 305 seems to go on longer.
My 405 started "low battery" around 6.5 hrs (abt as I finished). And it's advertised for 10 hrs. Drat -- but just lucked out there. Or I wouldn't have had a finishing time to record at all -- thinking I should take a regular watch in a pocket for a backup finishing time in the future.
No problems losing detail though. That might depend on some setting somewhere in the menu for granularity of data points (think I might have seen mention of that somewhere in the past).
It's a 5k. It hurt like hell...then I tried to pick it up. The end.

Janie, today I quit my job. And then I told my boss to go f*** himself, and then I blackmailed him for almost sixty thousand dollars. Pass the asparagus.
Bacon Party!
Heh... I've been pondering the same question. Even for a 50-miler, I think the 305 would be taxed. So, to get a 310xt too?
I dunno. I'm thinking about doing it the semi-old-fashioned way - with a watch (albeit an Ironman) and a list of project aid station times.

And...
succes with the 100 miler
I believe that some of the newer Garmins have a better battery life. The 310XT is supposed to last for around 20 hours. I haven't tried it though.
yes, this was mentioned in the original post. Mine lasts about 15ish hours.
Buy a Polar. It works perfectly without ANY work-arounds. My RS800CX lasts 30 hours on a single Lithium AA battery. If it dies during the race, you swap out the battery and go on... it picks up right where it left off (the watch is separate from the GPS, so the watch keeps on recording while you swap batteries, then the GPS starts transmitting data points again, and you're good to go).
I LOVE mine. I've had it a little over a year, about 2600 miles, and haven't had a single issue. It's *so* much better than the Garmin ForeRunners.
It also doesn't truncate the data like the Garmin. You set the recording interval (1, 2, 5, 15, 60 sec) and you can get up to 100 hours of data. 15sec recording intervals will get me through any 100 miler.

Would a solar USB charger work?

Heh. I've actually considered rigging a system that puts the solar panel on my friggin' hydration pack and plugs into the dumb watch. It was a fleeting thought, but it rattled around in there for more than a few seconds. Yes, that's how addicted to my Garmin I am. I'm not wanderlost for no reason.

Mine craps out at about 6.5 too.
