Seth Peichert paddled his kayak nearly 1,500 miles from Miami to Baltimore.
He started in April and finished over the weekend.
Peichert says in the process he lost 20 pounds, got a leathery tan and grew a thick beard.
Along the way he slept on the beach, encountered alligators and dolphins, and was stung by a jellyfish.
So, why did he do it?
The 24-year-old kayak guide says his marathon paddle was a personal challenge.
