I was thinking about getting a GoPro for my thru-hike and adventures beyond. My query concerns the thru-hike. I solved the problem of running out of power by carrying an external battery, but not running out of storage space. I could carry multiple SD cards, but the quality of high resolution footage means spending $65 per 64GB SD card. That is more than I can spend. I assume uploading data to cloud storage in town is unreliable.
I've seen lots of videos taken on a thru-hike and was wondering how people handled dwindling storage space. Does anyone have experience with this?
