A while ago, I was recording a round-trip through my backyard with my GoPro HERO 9, to be shared with those of you who would like to create a Real Life Video (RLV).
If you are on an indoor cycling platform that supports using your own, like Rouvy or BigRingVR that is.
I had a route in mind that would be just under two hours, which would be more than enough for most indoor sessions.
