wilderness, but often times you're the first people. >> reporter: the next big adventure? a 1400-mile paddling trip, less than 500 miles from the north pole. bradt hasn't lost his taste for waterfalls but he says he's not going to try to break the record. unless someone else breaks it first. it's amazingly adventurous stuff. i can't help but think, what propels you to do this, the risk of being hurt, drowning, dying, people's survival instincts sort of take over. yet you do this very dangerous stuff. why? >> there is no experience like it. i started kayaking at a very young age. it's been my soul focus ever since then, and there is -- the places you're able to go, the experiences you're able to have, and just the sheer thrill of being out on a river and running white water is absolutely unreal. and so it's -- that's my driving force. i just love it. every aspect about it.
