Over €2.2 million has been raised by the Climb With Charlie.
The former broadcaster climbed Croagh Patrick in County Mayo with a crowd of supporters last weekend to raise funds.
The money will go towards the Irish Motor Neurone Disease Association and Pieta House.
Because of the generosity of people all over Ireland and abroad we are on course to reach two and a half million euro.
Donations open until the end of May.
I am asking Corporate’s if they would help to reach a target now of three million euros for the two charities.

The journalist, who was recently diagnosed with MND himself, said the experience was one of the "most amazing" of his life.
He has also suggested that they may look at producing a book of photographs featuring images from the different Climb with Charlie events from around the country.
