Co operation North expects to raise more than £60,000 from this year's Dublin Belfast maracycle which took place over the weekend. The 2,500 participants left from either Queen's University Belfast on Friday morning or from Dublin on Saturday to cycle the 200 miles between the cities.
RTE presenters Myles Dungan and Carrie Crowley joined the cyclists for the Dublin Belfast leg of the 14th annual maracycle.
This was the first year of the "mini cycle" which covers 25 miles and was introduced for those unable to do the full route.
A few hundred people took part in the shorter mini cycle from Banbridge to Queen's PE centre and from Drogheda to Dublin Airport.
