A cyclist has died after taking part in a 100-mile annual charity bike ride from Cardiff to Tenby.

Event organisers say Mr Gronow suffered the medical emergency after leaving Johnstown in Carmarthenshire.

Emergency services were said to be on the scene "almost immediately" but he could not be saved.

A statement from the organisers said: "With deep sadness we can confirm the passing away of a rider in the 2024 CARTEN100.
