Thousands of runners will hit the streets of Sussex today for the fifth annual Brighton marathon.
World-record holder Paula Radcliffe will officially start the race. The event is expected to attract over 10 thousand runners.
Two extraordinary people will be among more than 10,000 men and women running the Brighton Marathon on Sunday.
He calls it "joggling" - running and juggling at the same time - and Kevin Williams plans to do it for the entire 26 miles of the Brighton Marathon.
All the more amazing considering that five years ago he suffered a massive brain injury after a fall. He awoke from a two week coma with no idea who he was.
The damage to his brain was so severe, Kevin had to relearn to live from scratch. His only asset a basic muscle memory.
We caught up with him training on Brighton seafront. You can sponsor him here.
Amanda Chalmers was born with cystic fibrosis and will run the Brighton Marathon less than two years after undergoing a double lung transplant.
The 26-year-old University of Brighton graduate could hardly walk up the stairs before her life-saving operation in September 2012. She'll be raising money for the Cystic Fibrosis Trust.
We caught up with her while training in nearby Preston Park. You can sponsor her here.
As the Brighton Marathon was taking place last year, Andy and Emily Squires from Hove had just been told their 8 month old son, Thomas, had meningitis. As they watched the race from the hospital window, they vowed that whatever happened, they'd take part in this year's event.
Another chance to see this report by Charlotte Wilkins.
As many runners out there will know we are nearing the marathon season and many are in training ahead of the Brighton marathon which takes place in April.
When the race was under way last year, Andy and Emily Squires from Hove had just been told their 8 month old son, Thomas, was suffering from meningitis.
As they watched the crowds from a hospital window, they vowed that whatever happened, they'd take part this year. Charlotte Wilkins has their story.

A film-maker whose best friend was killed while serving with the 2nd Battalion the Parachute Regiment will run next year's Brighton Half marathon in his memory.
Christian Hearn lost his best friend of 16 years, Private Daniel Prior, in 2011. The 27-year-old was injured in Afghanistan by an improvised explosive device. He was returned to the UK, where he died in hospital.
Christian and Daniel had been keen running buddies, training and covering many miles together in and around their home town of Peacehaven in East Sussex.
Christian will be running in aid of Blind Veterans UK, which has its oldest support centre in Ovingdean, Brighton.
The 29-year-old said: "As Dan served with the Parachute Regiment it made sense for me to want to support a military charity.
"I have done four half marathons before but never the one in Brighton. I have done ones that are really hilly and bumpy so running on Brighton's flat ground this time should be good.
"Me and Dan really got each other running and would always go out running together. We always spoke about running marathons and half marathons together but never got the chance to. I like running in his memory."
The Brighton Half Marathon takes place on February 16.
A Brighton marathon runner died following a reaction to sports supplements and ibuprofen, according to a coroner.
Sam Harper Brighouse, who was 23-years-old, collapsed around 16 miles into the run in April. The coroner recorded a verdict of misadventure.
The runner was originally believed to have suffered a cardiac arrest.
Sam was running the marathon to raise money for the Arms Around The Child charity which supports Aids orphans. Donations are still being made and have now reached over £33,000.
Donations on the fundraising page of a 23-year-old man who died after collapsing during the Brighton Marathon have reached £18,000.
Sam Harper Brighouse, from London, is believed to have suffered a cardiac arrest at about the 16-mile mark of the marathon on Sunday.
More than 1,300 people have now made donations to his justgiving.com page - far exceeding its fundraising target of £500.
His site states that he had embarked on the challenge to raise money for the Arms Around The Child charity which supports Aids orphans.
