Thank you ladies. I did learn from this that I need to prepare myself as much as possible for the ride. Which means driving the course (if possible) so I don't suddenly stumble upon 'the Alps'. And I did learn a good bit from the mechanic when I needed some adjustments, which made my riding easier. I've decided I need to do a lot more reading about nutrition and also learned I hugely underestimated the amount of food I need to keep myself functioning on a ride.
