Good footage Damon, nice to see you getting some air on the whoops. The gaps between the trees are unpleasantly narrow compared to the handlebars in places.
The 2 stone loss comes from the uphill slog back to the carpark after 4 minutes of wild downhill fun, I loath that bit. Got to make sure you dont offset that with the bacon butties at the cafe.
Sorry to hear about your difficult situation, best of luck.
