Brian's pretty amazing - he does about 2 races each year, and no other running. Like not farther than the length of a basketball court. Yet he still does pretty well!
He ran this 5K - while pushing the big stroller and 80 pounds of children - in about 27 minutes! And last year he did a 10K in about 55 minutes.
But it's still good for his cardiovascular system to do something a little crazy a few times each year, right?
I can't wait til someday all 5 of us are running stroller-free!
