Glad you all enjoyed the video. I am incredibly lucky to live in such a beautiful part of Scotland. Yes it is hilly, this is one of the flatter routes! Mostly you spend all day riding rollers with the occasional big hill. The first hill in the video that starts around 10 minutes in goes up to 17% at one point. I can just about get up it without any wheel slip now. The other big one is the climb out of Innerleithen that starts around half way through - that's a 7 mile hill that starts around 1% and slowly gets steeper as you go. It's never that steep but it's quite long.
@Don1 yes I got a few PRs on this ride - weirdly, I have done this same loop 2 minutes faster, on 11 watts less. This ride was average 212 watts. I'm trying to sit at 220 watts in general riding, pushing up to around 250 on the hills. Difficult on some of the back roads as there's so much crap on the roads and I get hesitant about powering through.
The last 8 miles, I take the main road back into Stow (the very small village I live in, you see it right at the start and end), and use the better road quality and flatness to put a nice sweet spot / threshold interval in. I manage about 270-300 watts down there, then my legs are toast
