I raced alongside them for a few miles of the Run 4 New Years' Day race in 2005. After blowing by me around mile 3, they ended up finishing 2 minutes ahead of me. At the finish Dick shook my hand, and thanked me for "racing" with him. I chatted with them a bit, and admittedly I was a bit starstruck. Their legend here in Massachusetts was well known to me even before I was a runner.
The Hoyts are amazing, and Dick is one of the most gracious, humble people I've had the pleasure to meet. You can read more about them here.
