Why go on about marathons?

Only about 3% of all organized race finishers are marathoners.

The half marathon is the fastest growing event in the world. There are now far more more Half Marathon finishers in North America than 10 KM finishers. 

There are almost four times as many half marathon finishers as full marathon finishers.

Half marathon is a challenge while still leaving room in life for some sloth, beer and chocolate. Marathons are a lifestyle choice.

Marathon participation is actually pretty small in the big picture, so the author's wish is essentially already moot.

I've run eight marathons (survived might be a better description) and about 150 half marathons.
