Colm O'Neill


Colm was the second swimmer from Ireland, after International Marathon Swimming Hall of Fame Honoree Ted Keenan, to complete both the English and North Channels. The English Channel in 2002 in 11 hours 42 minutes and the North Channel in 2004 in 11 hours 25 minutes.  Colm was the 8th solo swimmer to have conquered the North Channel in the years when it was rarely attempted. Only recently has this become a popular swim and with each success the pilots become more skilled and swimmers more knowledgeable. Colm’s status in the world of marathon swimming after the North Channel was extraordinarily high.

Colm completed Manhattan in 2008 in 7 hours 56 minutes.

In Ireland he was 2nd overall (fastest from Ireland in Lough Erne in 2003 in a time of 3 hours and 46 minutes), swam Inishbofin (7 miles) four times and holds the speed record for almost 20 years, completed Blackrock to Cobh (7 miles) and completed an Ice Mile in 2018.

He was part of “The Swim” – a relay across the Irish Sea in 2011 organised by Richard Branson which raised more than £300k for charity.  In addition, Colm was an active mentor to the Cork “aspiring” marathoners in 2004/5 and helped to kick start their success.
