According to Ultralister Jason Walz the following stats apply to 2007:

Number of 100s finished in 2007:

11 (1): Dan Brendan (Pictured right atAcross The Years)

9 (3): David Goggins, Dennis Drey, Hans-Dieter

8 (1): Phil Rosenstein

6 (3): Jack Meyer, Karl Meltzer, Rob Apple

5 (9)

4 (31)

3 (66)

2 (283)

1 (1641)

2679 total finishes; 2053 ultrarunners; 80% of hundred+ milers run only one race, and 94% of hundred+ milers run 1 or 2 ultras.

And Kevin Stroud added that considering the population of the U.S. is currently estimated at 303,559,949 that makes each of the 2,053 100-mile finishers "one out of 147,861 people."
