Matheson Brown doesn't mind discomfort. The 28-year-old from New Plymouth just smashed a world record, becoming the fastest person to climb the highest peak in every US state.
The clock started at Denali in Alaska, and didn't stop until he got to Mount Rainier in Washington.
This epic feat was achieved in 20 days, 14 hours and 4 minutes, with the help of his dad and two friends.
No second was wasted... they climbed at all hours of the day and night, sleeping for as little as an hour a time.
But it wasn't about the glory of holding a title.
Matheson Brown wanted to prove that regular people can achieve big things, even without major resource or professional backing. He joins Kathryn.
