More than £260,000 has been raised in Northern Ireland for the Children in Need charity.
Pudsey is the mascot of Children in Need
BBC NI has joined in a day of madness and mayhem with live radio and television shows and the main event got under way on BBC One at 1900 GMT.
BBC Northern Ireland presenters John Daly and Donna Traynor are hosting the show.
"With your help we can do great things for children and young people throughout Northern Ireland," he said.
Donna Traynor said she was sure people would do their utmost to raise as much money as possible.
"Each year people are incredibly generous and do some crazy and mad things for Children in Need and I am sure this year will be no different," she said.
BBC NI presenters Wendy Austin and Linda McAuley took part in the jog
"So come on Northern Ireland, get fundraising and help make a huge difference to countless young lives. Every penny really does help."
There was a truly musical feel to this year's television show on BBC One Northern Ireland, with Pudsey's Lyrics Board.
Team captains Peter Corry and George Jones pitted their musical wits against one another assisted by their teams of well known personalities.
There was also a very special message from Bruce Forsyth and the Strictly Come Dancing team, headed up by former dance students Gloria Hunniford and Denis Taylor.
In an exclusive, the pair teamed up for one night only to perform a jive in front of the discerning panel of Strictly Come Dancing judges.
Chart toppers Westlife are also in to Belfast to perform their former number one single You Raise Me Up.
The band's Nicky Byrne said they make a point of taking part in Children in Need.
"There's a couple of big charities that we always try to help out and Children in Need is obviously one of the biggest," he said.
"We've managed over the years to get to Belfast - or sometimes we've done it in London - to help out.
"Children are our next generation, so to help people like that out is brilliant."
Fundraising events got into full swing in Belfast
Another highlight was a one-off music special from the Northern Ireland football team, featuring Jackie Fullerton and George Jones, singing We're not Brazil, we're Northern Ireland.
Television cameras are out and about with outside broadcasts in Bangor, Ballycastle, Belfast, Bundoran and Irvinestown in County Fermanagh.
BBC Radio Ulster entered into the spirit of things as the Pudsey party raged from early morning, going right through the day to late in the evening for this year's BBC Children in Need.
Proceedings got under way at 0700 GMT on Friday with Good Morning Ulster presenter Wendy Austin leading from the front in the Bog Eyed Jog around BBC Broadcasting House in Belfast.
Presenters including John Toal, Joe Lindsay, Donna Legge, Lynette Fay and Hugo Duncan are broadcasting live from outside the main television studio until midnight with plenty of celebrity guests, great music and chatting to intrepid fundraisers.
Since 1980, over £10m has been raised on the night by generous donations and fundraisers in Northern Ireland.
