On September 8, 2013, 21 competitors from 12 countries toed the line to compete in one of the world’s most epic experiences. So epic, according to Wayne Kurtz of Pittsburgh, Penn., it would be one they’d never experience again. “This was a one-time gig,” he said.

Only 28 athletes from around the world were invited to participate in the 30 x Ironman, or the “Triple Deca IRON”. To prequalify, athletes needed to have at least one Deca IRON under their belt…and for good reason: the next step, from 10 days to 30 days, is quite a leap.
