Dun Laoghaire Harbour sailor Guy O'Leary is repeating last year's swim for charity endeavour this morning when he swims a mile each day during the month of May to raise funds for Cancer charities.
Like last year, he will be joined each day during the month by supporters that will complete the mile challenge.
In all, 70 swimmers from around the world will swim the mile and support the fundraising effort. Last year O'Leary raised €85,000 for cancer research.
As regular Afloat readers will know, O'Leary himself survived the disease after a year of treatment himself as he describes here.

Guy's fundraising page is now live at www.mileadayinmay.org you can choose to donate to Cancer Research UK or The Irish Cancer Society.
