An Edinburgh nurse has become the 77th person in the world to climb every mountain in the UK above 2,000ft.
The NHS worker says she would often leave the Edinburgh Royal Infirmary in the dark after a 12 hour shift in order to take on the challenge.
Sunny Huang moved to Edinburgh 16 years ago to train to become a nurse. She has now spent just two years climbing over 1,000 hills across Scotland, Wales, England and Northern Ireland.
