I don’t know what to say about handling sweat and rain, but I went running a few times with my airpods and also washed them a few times with and without case and they are still working :D
With my airpods I think I've gone a max of 8 miles in a single run and have only run into issues when the batteries are partially drained before I take off. I've gotten better over time about keeping them charged. I've probably done at least 60 or so runs with them and haven't had any issues.
I have to imagine they'd last up to a half marathon, but might struggle on a full marathon.
