I've since learned a few of those on the ride in my OP got into bother with the weather.
The plan was Sunderland up the C2C to Parkhead Station at the top of Weardale.
Most of us, including me, were in a poor state by the time we reached Consett, so took refuge in the cafe at Hownsgill Farm.
Five pressed on to Parkhead, to be met with even lower temperatures, yet more rain, then horizontal sleet and snow.
One of the lasses admitted she was in tears and unable to speak.
Fortunately, one of the group is ex-navy and used a bit of survival training, getting the rest to sing songs and keep talking.
Another of the lasses said later she would have been 'found dead in a ditch' if it wasn't for that support.
No long term harm done, and happily for me as the ride was my suggestion, everyone has accepted they took their own decisions.
But all of us should have known better, as locals we know if it's grim at Consett, it will be much grimmer further up.
