I used the GoPro HERO 9 Black's TimeWarp 3.0 feature to capture a recent bike ride on Holden Beach in North Carolina where I biked every street on the island. I tried to include the marsh loops as well, but they were very overgrown so I ended up just sticking to the streets. Overall the ride took about 3 hours for me and covered ~35 miles. I started at the East End of the island so that I just had to take right turns down the side streets (rather than starting from the West End and having to cut across traffic turning left over and over again). I am sure that this wasn't necessarily the most efficient route to cover all roads on the island, but I tried to minimize the amount of overlap (covering the same sections multiple times) as much as possible (although some overlap is inevitable).
