Ten members from the same Sussex family will compete in the Great South Run tomorrow.
The Cobbs, from Ditchling, will be among around 300 runners from the county in a 10,000-strong field running on the streets of Portsmouth.
They hope to raise £500 for The Martlets hospice in Hove.
Leigh Cobb, 22, Graham, 44, Daniel, 16, Richard, 17, Martin, 25, Susan,23, Charmelle, 26, Pat, 46, Darren, 27, and Adam, 20, are hoping to make it an enjoyable day out.
Pat explained: "We were inspired by watching the London Marathon on television earlier this year.
"My husband Graham and I both lost our fathers recently and we thought if we are going to be in pain then we thought we would all suffer together.
"We hope to raise quite a bit of money for a very good cause."
The family have been training along Brighton seafront and hope to return to the City for a triumphant evening out afterwards, because Graham's birthday is tomorrow.
Pat said: "None of our lot will be among the elite runners.
"Graham, Darren, Richard and Daniel will race between themselves as they are all fit. Leigh watched the London Marathon on video for his training."
Daniel is favourite to take the family honours and he is aiming for a time of one hour and 15 minutes.
He said: "I've had a bet with my dad, and I have to beat him by at least 25 minutes.
"I've got sponorship money from my rugby team at Lewes Tertiary College.
A more familiar face from Sussex will also be competing.
Former Albion manager Micky Adams is raising money for the Marie Curie Cancer trust and the Chestnut Hospice appeal.
Adams, before his departure to Leicester City this week, where he is No.2 to Dave Bassett, said: "They are two worthwhile charities and I am happy to put myself through a certain amount of pain for them.
"I try to run every day for about 30 minutes, that's about three miles a day."
Adams will be running with his ex-Brighton colleagues Bob Booker and Dean Wilkins.
He added: "It has been made into a bit of a race now. But I don't think the race will be between Bob and myself but rather Dean and everybody else, because he is that type of character.
"He is looking to do it in about one hour and forty minutes."
Other runners include BBC football commentators John Motson and Ray Stubbs, ex-jockey Richard Dunwoody, plus elite athletes like former Olympic 10,000m champion Khalid Skah and the Tanzanian Restituta Joseph.
The BUPA Great South Run starts at 1100am.
It is preceded at 9.15am by the BUPA Mini Great South Run and 30 minutes later the Junior event. The wheelchair race begins at 10.50am.
The run is over a ten-mile flat course which should make for fast times.
Increased security at all British military bases means it will not pass through the Naval Base.
Spokesman David Hart said: "The BUPA Great South Run will still start and finish on Southsea seafront. Race director Colin Goater has already adjusted the course and is hopeful it will still be exactly 10 miles."
