Dr Morgan, a mother of three, said that she became actively involved in organising school activities after seeing the enjoyment her own children gained from team sport.
She was nominated to carry the torch by a parent whose children are part of the Mumbles Life Guard Club and the Swansea Bay Hockey Club, which Bethan helps to run.
Dr Morgan said: ‘Life guarding is a great way for children to exercise and become aware of the potential dangers of the sea.’
She added: ‘It was such a wonderful experience to be able to carry the torch. I felt so lucky to be part of the experience and I plan to carry on encouraging children to be active.’
