The 34th Annual Children's Cancer Run, organised by the North of England Children's Cancer Research Centre (NECCR) is taking place today at Newcastle Racecourse.
Thousands turned out for the event, which has races for children and adults of different abilities.
The charity has raised £30m since it was founded in 1979.
Newcastle Racecourse is preparing to stage one of its flagship events this weekend - the Fighting Fifth Hurdle.
Last year's winner, Irving, is back to defend his title but Wicklow Brave, ridden by Champion Hurdle 2015 winner Ruby Walsh, is the current race favourite with bookmakers.
Tomorrow's Eider Chase at Newcastle could be a 'wide open race', according to the Clerk of the Course.
The Eider Chase is a 4m 1f race which is dubbed as a warm-up event for the Grand National at Aintree. Comply or Die won the event in 2008 before going on to win the National that same year.
James Armstrong, Clerk of the Course at Newcastle, says it's a strong field for the race.
Newcastle Racecourse has banned picnics for health and safety reasons for all its 2015 fixtures bar one following a number of problems at events last year.
The major racecourse, which attracts more than 20,000 people to meetings, will instead provide racegoers with a picnic site outside the racecourse but within the wider estate.
The venue's management team said stopping people from spreading out rugs and eating in chairs would ease movement around the racecourse and increase visitors' enjoyment.
The Blaydon Races in August is the only exception to ban against picnics or picnic furniture into Newcastle Racecourse.
Bookies favourite Irving won an enthralling race in the Newcastle Fighting Fifth. He got the better of Aurore D'Esruval
Newcastle Racecourse is expecting a 'strong card' for this weekend's Fighting Fifth.
The event, a Grade I National Hunt Hurdle Race, is one of the venue's showpiece meetings and the highlight of the jumps season at Newcastle. Many past winners have also gone on to taste success in the Champion Hurdle at Cheltenham the following year.
James Armstrong, the clerk of the course, is expecting a competitive line-up for Saturday's race. He said:
When asked which horse he believes will win the race, Armstrong added:
The Fighting Fifth takes place at 2:05pm on Saturday 29 November and the going is currently soft.
Tominator has won his second John Smith's Northumberland Plate after coming out on top in a close finish at Newcastle Racecourse.
The six-year-old, ridden by Graham Lee, won Newcastle's trademark event two years ago. He becomes the first horse to win the race twice in over 35 years.
Thousands of people flocked to see Madness perform at Newcastle Racecourse last night.

The band Madness help get a weekend of horse racing underway in Newcastle on Friday evening.
Fans sand along to classics such as Our House at Newcastle Racecourse
