Cogitating, now I am back in the saddle of my "goes like stink" inline 4 cyl, these are my current thoughts:-

Reasons not to join the club:

My state of physical health and general mobility is such that I have no inclination to undertake "hardcore off road" adventures (there's that noun again).
I am inclined to undertake off-asphalt riding only when the tracks under the wheels are in good condition such that I don't have to get off the bike and drag it out of the bog/mud or whatever (been there, done that and it doesn't hold my enthusiasm nowadays - connect with an earlier post).

I do like to stop quite frequently and enjoy the views + chat with anyone who is so inclined to do the same thing; hikers, dog walkers, geriatric pensioners out for the day, tractor drivers, anyone basically.
Consequently I also tend to ride pretty slowly to take in the views, and the potential views that may be coming over the horizon soon, while also absorbing the landscape, the ambience, call it what you will.
In my occasional foray with the TRF, years ago, I found this aspect to be of little interest to those whom I was expected to accompany.

Nor am I greatly inclined to even fall into line with a riding schedule set by ANO,"be there by such a time or we will depart without you".
Fine by me, be gone and I will carry on regardless with both my life and my riding.

It seems that some have had less than satisfactory experiences with their contact with the TRF. All I can say is that mine have mostly been superb.

There are runs that are planned to crack on at a reasonable pace to cover ground or get a little further afield and others are a more relaxed. The old(er) boys I ride with sometimes, still do many technical lanes but with more comfort breaks and instead of lunch being a pasty in a garage while fueling up, it'll be sat on a hill somewhere picturesque.

Be honest about your ability and what you want out of the day and don't be afraid to say that you're knackered and could do with a rest.

I know that I wouldn't have had any where near as many spectacular experiences if I'd just got a map and bumbled about on my own.
