He represented his home country in the 2023 World Athletics Cross Country Championships where he led his team to a bronze medal in the (U20) Junior race a week and a half before his 18th birthday. His 16th place was the highest from a non-East African country. He qualified for the World Championships by winning the U20 race at the USA Cross Country Championships. While running for Newbury Park High School, he was the only person to be a part of three National Championship cross country teams over a four-year period, interrupted by the COVID-19 pandemic. Each of those races was won by a teammate, his older brother Nico Young in 2019, Colin Sahlman in 2021, and Aaron Sahlman in 2022. Leo was the last competitor each of the Sahlman brothers passed en route to their victory. With Aaron, Colin and twin brother Lex, his team set the National 4x1 Mile run record. Their time of 16:29.31 took seconds off the previous mark. Leo ran a 4:00.77-mile as a high school junior. Lex and Leo are Youtube vloggers, documenting their adventures including training and racing under the handle L&L. 2019 At the Nike Cross Nationals in Portland, Oregon, Leo was the lone Freshman on the champion Newbury Park team led by his brother Nico, then a Junior.
