Some have said that the accomplishments of runner Ed Whitlock rival Roger Bannister's breaking of the four-minute mile barrier.

In 2000, at age of 69, Ed became the oldest person to ever to break three hours in a marathon

Last year, at the age of 74, he once again finished a marathon in under three hours.

He talked to the Growing Bolder Radio Show from his home in Canada and discussed what records he plans to smash next.
