The family moved to Reno, Nevada, in 1979, where he ran his first marathon in 1982. They are both retired and currently reside in Sarasota, Florida, and have two sons and three granddaughters.

He has run 381 marathons in 130 countries. He has completed a marathon in all fifty states, DC twice, and four US territories; all thirteen provinces and territories of Canada, and all seven continents.

He has completed a marathon in every country in Europe, North America, South America, and Oceania, and he has completed at least one marathon in at least eight countries on every continent—except Antarctica, which only has one country.
