Your audio is great at the pace you were riding at. You def need to try and keep the videos under 15min if you can, and try and structure them. I got to just over 10min into that and you could have put in a close out and finished it there. You then could have done a new opener and talked about the new subject and closed it out after, and done that all the way through the ride. That would have gotten you 5 vids for your channel along stunning roads and scenery (assuming the scenery was as nice all the way through?), which would have given you 5 weeks of content to share if you are doing one a week. If you are then able to get out a lot and ride still, you could either bin or bank the videos you liked less for a "rainy day".
What FOV where you using on your GoPro Hero 8?
Awesome first vid, you seem very comfortable talking while you ride. If youcould afford it,you could mount a second camera facing you so that you can cut to it to remove the "yeah umm" and the sniffs etc, we all do the "umms" and sniffs/sneezes etc, but it is nice to be able to cut them out if you are able!
Awesome stuff
