The chair of my running club has a bee in his bonnet about us all carrying contact details of someone who could come and pick us up, if needed, when out on a run. I can't think of anyone.
There are people who would need to know if I had an accident, and there are a few people I could ring round if I needed help in an emergency, but there's no one who would reliably drop everything to come and get me.
I have a BF, but he is very much BF, not partner and in any case he would usually be out running (in a different group) anyway.
I have young adult DSs but one lives 300 miles away and the other doesn't drive.
I have parents, but they are more or less housebound.
So my emegency plan is if I can't help myself, someone had better call an ambulance, or if I can, I'll either ring whichever friend is most like to be available at the time or call a taxi.
Surely this is likely to be the case for most people not in long term relationships? There's no one waiting at home for the call?
