Mark your calendars; the 2006 ING Amsterdam Marathon is almost here. This Sunday, October 15, thousands of runners will take on a huge challenge. The route meanders through Amsterdam's city center, and is a great spectator sport as well as an athletic challenge for those participating.

Runners can choose to run the full marathon, a half marathon, or a 10 kilometer run. There's even a 2.5 kilometer youth run. Yours truly will be attempting the half marathon, for the first time.

It is even possible to register up to the day of the race. So if you're up to it, move quickly! More information can be found here.
