Least you were smart and brought tools with you, would have been a long hike back dragging a bike with flat tyres otherwise!
Still looks like a nice ride through a nice area even though you understandably didn’t feel up to exploring much after that fiasco 🙃
Yes, it would be a problem. It already has happened in the past, although not that far away. Since then I keep taking the tools with me if I/we go a bit further out.
