Arthur Serrières (FRA) and Solenne Billouin (FRA) defended their titles at the 2023 XTERRA World Championship in Trentino, Italy to extend their reign as XTERRA World Champions for a second year running. With the skies clearing over the cool, clear, crystal waters of Lake Molveno, over 100 elite off-road athletes dove headfirst into the 27th edition of the XTERRA World Championship. But it was Arthur Serrières and Solenne Billouin who were able to return first to capture the title for a second year running.
