> You're right, I haven't. So how people do you think there are in the UK that compete regularly at 100m? The world? Yes, javelin would certainly fit my theory (putting aside confirmation bias).
OMG. This stuff is fascinating. It all depends on your own perception and experience. However; when I was into athletics (late 70's / early 80's as a late teenager), there was competition to get into the Gateshead harriers sprint team at all age groups up to about 50 (male) and 40 (female). Jarrow AC were less than 5 miles away, with similar numbers.......etc etc. So in the local league, which had 3 divisions of 8 teams each, there would be regularly 32 competitors per event per age group. In a local league in the north east. Were we any more athletic than anywhere else? I would say not, as I went to Uni in birmingham and it was a similar set up. there were 5 or 6 big clubs just in birmingham itself. I drifted off into other sports (climbing / volleyball), but extrapolating across the country, literally thousands took part in competitive sprinting each week. I could run sub 11s for 100m and couldn't get into the gateshead u20 team. But competed in high jump and hurdles.
more recently, daughter No 2 was into running and went along to a few meets with the local AC. There were more seniors/masters age types than school age competitors. So its still as popular as ever.
When you look past the glamorous national / international events there is almost always a surprisingly large number of participants in a sport. Look at climbing - not that many compete at national level, but look at how many enter bouldering leagues etc i did a few years ago when on the BMC comp Comm, and the number of regular competitors in local comps was way over 10,000. And we are no different in the UK to pretty well anywhere else.......
> Looking at the other side of the coin, what do you think might be the highest participation sport that is *NOT* in the Olympics? For given given definition of 'sport' of course! Squash? Darts? Fishing ?
Possibly squash because of its global reach, possibly bowls, but doesn't have a global reach (but lots of variety of very similar sports), or perhaps netball? That's one sport that maybe doesn't get into the olympics because of its lack of global coverage, but should be in because its massively accessible in terms of equipment needed (a ball) and participation would go through the roof, especially amongst populations without easy access to equipment.
