In the interim - -
Find someone to go on a local walk/ hike once or twice a week.
That's much easier to do and does wonders for your outlook.
But, yes, it is really, really difficult to find like-minded touring buddies.
(Especially at our age, but let's not mention that.)
I can't tell you the number of time people have bailed a few days before the start of a tour.
I could usually see the telltale signs weeks before, so it was never that much of a surprise.
I tour self-sustained and low-budget.
A few years ago, I did tour with a friend who was a roadie and had never done a big tour.
We rarely got 10 or 15 miles in before noon - then rode past sundown to reach our destination.
I love the early morning time for riding - best time of the day.
So, even then it was not a great fit.
I think it is the nature of the beast.
