26.2 states the distance of a full marathon (26.2 miles). I placed this on my car after finishing my first marathon on January 2010. Obviously after doing a half iron distance triathlon on November 2010, I was due for a deserved upgrade.

Upgrade: 26.2 miles (marathon) to 70.3 miles (half iron triathlon)

Will I double that number in November 2011 to 140.6 miles? This is a great way to keep motivation up! (Plus a great conversation topic when people ask what those numbers mean ;) )
