Subject: How many Ironmen are there?
Does anyone know if there is a count on how many Ironman finishers their have been since the first race? I know it wouldn't include the non-IM branded events. Just curious.

Try searching past posts. This was discussed a number of months ago, It's a rather detailed calculation.
If you find out post it, I googled it and found nothing.

According to this forum, 500,000 marathons completed per year.  I think IM is less than 1/10 of that.....so maybe 50,000 IMers per year.

Another ball-park is this:

Estimate there are 75 formal Ironman races per year in the US.  Then estimate 2,000 participants and 85% finish rate.  Comes to 127,000 finishers per year.  Hmmm, that sees a little high.

Ever estimate the number of Piano tuners in Chicago? 

http://en.wikipedia.org/wiki/Fermi_problem

Suprisingly accurate.

So I stand by my estimate of between 50k and 127k finisher per year.

75 per year? That seems really really high.

Only the IM branded races hold 2000 of us, most are in the 500 and under ballpark.

OK, the OP asked for the number of finishers since the firrt IM.  Here is my estimate:

75 is probably too high for the number of races.  With the exception of CA and maybe TX, assume not more than one IM per state.  Let's say 35 of the 50 states host an IM event.

Let's say 1/2 of those are M-dot and hold 2000 = 35,000 and 1/2 hold only 500 so another 9,000. 
 
Total 44,000.
 
Now lets say 1978 till 2008 = 30 years.
   
Let's say IM events grew linearly from 1 participant in 1978 to 44,000 in 2008.
  
OK, need Excel now....

MDot races in US

AZ
Lake Placid
CDA
WI
KY
FL
Kona

Am I missing any? 

IM Canada 

 No where near half the States having MDot races.

7 in NA w/o including Kona since most folks qualify to get there. So 7 races x 2500 of which about 50% are first timers. So 1200x7= 8400 new Ironman per year in north American M Dot races. 

I think in US there are about 5-7 other IM distance races that are not M Dot races...

OK, so this will reduce my starting number by about 75%.

 

So this would yield a new estimated grand total of 369,000 x .25

Well, let's just call it an even 100,000.

Considering that is spread over 30 years, that is not many!
