TL;DR
WL in track and field stands for World Leading, representing the best performance globally registered in a specific event during the current calendar year, according to official governing bodies such as World Athletics.
This elite status highlights exceptional athletic achievement, with distinctions made for various performance metrics like personal bests (PB) or season's bests (SB) that fall below the WL standard.
For instance, in 2025, Habtom Samuel's 8k championship at Gans Creek Cross Country Course in 22:12.4 would be a prime example of a performance vying for WL status in cross-country.
