I don’t know whether there’s anything we can do at this stage to support Simon, or his family.
But I would really like to see more people doing first aid courses. Not just basic workplace courses, but proper outdoor first aid, where an ambulance won’t turn up in 5 minutes. Something like the REC course.
Then if something similar happens to one of our mates, we’ll know exactly what to do.
Edit: I’m not implying Simon’s companions didn’t do all the correct things. I’m told that on both occasions, Simon was lucky enough to have professionally-trained first aiders riding with him.
