There are two channels I watch regularly, both coincidentally made by female walkers. In both cases the videos focus on the walking rather than equipment. I am not a fan of kit reviews at all.
The first is by the infectiously enthusiastic Abbie Barnes. I know that there are many on this forum who also watch her videos. I particularly like her National Trail reports.
The second is by an American lady called Jessica Mills whose channel is called "Homemade Wanderlust". She has produced some stunning videos on the big three US Trails which she originally released as weekly reports. She has also condensed the AT and PCT into single hour long presentations. She only finished the CDT a couple of weeks ago so it will be a while before a condensed summary of this appears. I do post videos on Youtube myself and this channel is what I would like to aspire to.
