FORT WORTH, Texas - Simone Biles enters this weekend's US Gymnastics Championships as the favourite to claim yet another all-around title as the sport's most dominant force continues to build momentum ahead of the Paris Olympics.

The four-time Olympic gold medalist is gunning for a record-extending ninth US title at the competition after her 2023 triumph saw her break a tie with Alfred Jochim, a two-time silver medalist at the 1932 Games.
