This year's London Marathon will have a non-binary category for the first time.
Organisers say they're making the change after an extensive review to make the event more diverse and inclusive.
The elite athlete races, which operate under World Athletics rules, will remain restricted to male and female runners.
For the first time, a non-binary gender option will be offered to applicants in the 2023 TCS London Marathon Ballot.

In a statement released this afternoon they say the three gender options (male, female and non-binary) will be offered to all participants registering for the mass participation element of the TCS London Marathon via other entry routes, including charity entries.
Hugh Brasher, Event Director of the TCS London Marathon, said: “This is a significant step forward for the TCS London Marathon as we continue our journey to make our event truly inclusive.
“We know there is still much more to be done, but changes such as this demonstrate our commitment to making the TCS London Marathon an event that is for everyone.”
The 2023 TCS London Marathon will take place on Sunday 23 April.
The ballot for the event will open on Saturday 1 October, the day before the 2022 TCS London Marathon on Sunday 2 October.
