A British lawyer has died while sandboarding down a 330ft dune on a fitness camp holiday in Namibia, Africa.
Claire Lee, 34, was attempting the extreme sport for the first time while visiting a fitness camp in the Okonjima safari reserve.
Mrs Lee completed the run, but the mother-of-two collapsed at the end of it. Fellow tourists attempted to revive her to no avail.
Beth Sarro, founder of Alter-Action Sandboarding, the Namibian firm that organised the session, told the Metro: "She completed the run safely but said she felt funny and then she just collapsed.
"We were told afterwards that she suffered from a pre-existing heart condition."
Claire, who lived in Guernsey with her husband, was one of a group of tourists travelling with her personal trainer Jon Le Tocq, whose firm, Storm Force Fitness, organises trips to the retreat.
Mr Le Tocq said Mrs Lee had died while sand boarding at Swakopmund, west of the capital Windhoek, last Wednesday.
Mr Le Tocq told the BBC: "Our thoughts and deepest sympathies are with the family of our friend.
"She was a member of our small group on holiday in the country. At this time we are unable to comment further."
Her husband Barney, a partner in Guernsey law firm Mourant Ozannes, was too upset to discuss the incident.
The company's managing director, Jessica Roland, told the Daily Telegraph: "We are devastated by the news and our thoughts and prayers are with the family."
