Tuliamuk surprised the running world when she won the US Olympic Marathon Trials in February, beating a strong field that included 2018 Boston Marathon champion and two-time Olympian Des Linden and half-marathon American record holder Molly Huddle. Tuliamuk, who was born in Kenya and became a US citizen in 2016, is a 10-time national track and field champion in events including the 25K, 20K, and 5K. Her Olympic Trials victory represented an inspiring comeback from injuries that left her driving an Uber and crocheting hats that she'd sell online. With a powerful story and undeniable speed, Tuliamuk will be a formidable force to watch in Tokyo.
