It’s not an event normally seen in Massachusetts, but that didn’t stop Adam Bonfilio from proving he’s one of the top track and field athletes in the country.

The octathlon is a collection of eight events, one-day version of the decathlon but without the discus and pole vault, and the 1,000 meters instead of 1,500.
