Marathon Math

The Houston Marathon route goes right past our street corner. The kids love to watch the runners and cheer them on (sometimes bringing out the musical instruments for extra entertainment).

This year, one of our good friends ran the marathon. The boys had a great time tracking her progress on the internet. Because of the microchips on the bib numbers, every runner can be tracked on the internet as they pass each 5 kilometer checkpoint.

As we were eating lunch, our friend passed the 30K mark. Joseph thought for a second and then said, "So she's gone 18 miles." Which, after considerable deliberation, Cort and I figured out was pretty much right.

So we asked him how he figured it out. He said, "Well, Mom ran a 5K and that's 3 miles. So there are 6 5Ks in 30K. And 6 times 3 is 18."

Yep. Math is definitely his strong subject.
