1 . Liam Gamer was just 17 years old when he started out on his big adventure—a 32,000-­kilometer bike trip from Alaska to Argentina. In early January, 2023, he finally finished his trip, 17 months after he started.

Liam, an experienced cyclist, had previously ridden from Los Angeles to San Francisco. He made short videos of that trip, and shared them on the social media app TikTok, some of which became quite popular. After reading a book by adventurer Jedidiah Jenkins, who biked from Oregon to Argentina, Liam decided to cycle from Prudhoe Bay, Alaska, the northernmost point in the United States accessible by road, to Ushuaia, Argentina, the southernmost point of South America.

Liam set out on August 1, 2021. At first Liam’s parents weren’t too happy about him taking such a long bike trip by himself though it wouldn’t take that much money. But as he carried on, his parents became his strongest supporters.

After about three months, Liam had crossed the US, going south along the West Coast. By early December, he had reached Mexico, from which his parents came to the US many years ago. “So crossing the entire country on a bike and reconnecting with my culture and learning the language in the place my family is from is so deeply important to me,” Liam explained emotionally. But Liam also faced challenges in Mexico.

He was robbed in Mexico, and at one point, he considered quitting because the incredible heat made biking extremely difficult. In all, he was robbed five times on the trip. He got very sick more than once. In Colombia, he had a bike accident that left him injured and required surgery. In spite of it all, he kept going through rain, sun, heat, cold, deserts and mountains.

Liam finally arrived in his destination on January 10, 2023—527 days after he started. He had travelled through 14 countries along the way.
