Journalist Charlie Bird has thanked "everyone across the country" as his Climb With Charlie campaign surpassed €1 million in donations.

The retired RTÉ broadcaster and his team of supporters will climb Croagh Patrick in Co Mayo tomorrow to raise money for Motor Neurone Disease and Pieta House.

According to the climbwithcharlie.ie website, the fundraising total has now topped €1 million.

Vicky Phelan yesterday sent a special message to "her good friend" Charlie Bird to wish him well on his 'Climb with Charlie' project this weekend.

She also expressed her disappointment that she will not be able to join the journalist on the challenge due to ill health.

There are over 150 climbs taking place across Ireland - and the world - this weekend as part of the campaign.

Thousands of people are hitting peaks at home and abroad, with charity climbs and walks planned in the US, South Africa, Australia and Spain.

Following Charlie's terminal diagnosis with Motor Neurone Disease he decided to set up Climb With Charlie to raise funds for the two charities very close to his heart, Irish Motor Neurone Disease Association and Pieta House.

The campaign has captured the public’s attention with the view to showing support for any person who has to climb their own physical and mental mountains in their daily lives.

Earlier today, Mr Bird expressed his thanks to "everyone across the country and in many places around the world" for their support.

He tweeted out a video from near Croagh Patrick while sitting in the sunshine with his dog Tiger.

An Irish tech company developed the software that allows the journalist - whose speech has been affected by MND - to get his voice back.

Marino Software used RTÉ archive clips to put together a "voice bank" of words and phrases that Mr Bird can now use to communicate.
