Latest extreme sportsman to perish doing wh at they loved

IAN McKeever is the latest Irish adventurer to lose his life over the past few years. Others who died include:

Paraic Casey: The 45-year-old swimmer from Cork died while trying to swim the English Channel last July. He was within a few kilometres of France.

He was an experienced swimmer who was in "great shape" and had done more than 2m metres of training in the past year.

He was a member of the Sandycove Ireland Swim club at the Kinsale Estuary in Co Cork and had been raising money for St Patrick's Marymount Hospice in Co Cork and St Vincent de Paul Society.

John Delaney: The father of three (43) from Kilcock, Co Kildare, died in May 2011 while trying to climb Everest, days after his wife gave birth to a baby girl.

He collapsed less than 50 metres from the top and was the first Irishman to die on the world's highest mountain.

Delaney died without knowing his wife Orla had given birth. He had been mountaineering for several years and was attempting to conquer Everest after a failed attempt five years before.

Ger McDonnell (37), was the first Irishman to reach the summit of K2, the second highest mountain on earth, on the border between Pakistan and China.

He lost his life with 10 others after an avalanche on the descent, in the worst single accident in the history of K2 mountaineering, in May 2008.

He was born in Kilcornan, Co Limerick and a decade before his K2 success, moved to Anchorage, Alaska, to work and develop his skills as a mountaineer.

The high-altitude climber was killed while attempting to rescue three others.

The Gerard McDonnell Memorial Fund sponsors the children of the sherpas who died.
