Didn't. I cancelled the ride due to the forecast last night. Nobody expressed any interest anyway. Probably cancel tomorrow as well. Weather is not helping. But lack of interest is disheartening. I'll do a local run in the week if the weather clears. I've put details on five forums but this is the only one that commented.
Happened across this looking for something else but thought I'd add a virtual shoulder to the wheel - don't give up, keep the faith, it'll take time, you're doing a good thing.
I'm probably 8/9 miles away from you so it's probably not for me, but as you say facebook isn't necessarily the best place to find cyclists of a similar mind - but then again where is? Obvious answer is your local cycling club... Could infiltrate & form a splinter group of disgruntled veterans?
I'm quite fortunate in that there are half a dozen blokes local who ride regularly and we're not poles apart fitness-wise, plus we all have kids around the same age in the same school so we're in regular contact anyway.
There's quite a strong community up near us so I plan to do something similar to you, but as there's already a 'core group' it should be simpler to swell the numbers... time will tell!
