That looks a decent (if heavy) setup, vantage.
I've done the same thing a few times - I've got the bike ready and taken ages packing everything, then gone "sod it" and went home. The most was Kirkby Stephen, which made for a near-100 mile day ride with a camping load
- the least was about three quarters of a mile into a headwind. If you're not in the mood, you're not in the mood.
