A walking group in the Brecon Beacons has gained 17,000 Facebook followers in just two years.
Walking the Brecon Beacons was created by former miner Dai Powell in August 2016. Since then, the group has swelled to huge numbers with many online followers and lots of people joining the walks themselves. Mr Powell cannot believe how popular it has become:
Members of the group say that regular walking has improved their physical health with some reporting weight loss. Other members say the group has been just as important for their mental health.
The group also provides a support network.
Walking the Brecon Beacons organises guided walks for people of all levels and Mr Powell says you do not need to be fit to join: He says there are a lot of beginners walks and no experience is needed.
The group is free to join but any donations made go towards extra training or first aid courses.
Due to its popularity the group has been extended to coastal walks and some in North Wales.
