(Reuters) - British sprinter Dina Asher-Smith believes that Florence Griffith Joyner's long-standing 100m world record could be in danger this season due to considerable advancements in spike and track technology.

Griffith Joyner's controversial mark has stood for 34 years after the American ran 10.49 seconds at the 1988 Olympic trials. She also set the 200m world record in Seoul later that year, winning in 21.24 seconds.
