Here's the challenge, to run around the British Isles in 80 races in a calendar year.
That was the task facing editor of the Swindon Advertiser and keen runner Dave King, who decided to spend 2007 in search of races the length and breadth of these fair isles to seek out the characters and culture of the sport.
Dave's book, "Around the British Isles in 80 Races" (AuthorHouse) has just been published with all the proceeds going to an autism charity.
In a light-hearted and whimsical read, which Dave describes as a bit like "Alan Whicker with running shoes", he sets about on his grand tour beginning with a 2km race in Derbyshire at three minutes to midnight on New Year's Eve.
There are a few fireworks and some rain on a low-key start to this madcap adventure which takes in races as grand as the London Marathon and the Great North Run, historical events such as the Braemar Highland Games and the Blaydon Races, fearsome sounding challenges like The Grizzly and The Terminator, to the downright weird such as Race The Train in Wales and the Chiquita Bananaman Run, when Dave dressed up as a banana to be chased by hundreds of runners.

Dave, a member of the south coast-based club Stubbington Green Runners & AC, raced with inmates inside a prison, went hashing through flooded fields at night, raced with a dog, climbed bone-jarring mountains and ran through icy-cold rivers on a journey which took in races in England, Northern Ireland, the Republic of Ireland, Scotland and Wales.
He also took part in a number of races with his 10-year-old son Ross, who is severely autistic, pushing him around the course in a specially-adapted sports stroller.

The journey finished just where it began, in Derbyshire 12 months later for the 2km run on New Year's Eve.
"The whole point of the project was to raise awareness and funds for autism which touches the lives of half a million people in the UK," explained Dave, 45, who lives in Swindon. "Running and travel is something I enjoy, so here was an ideal platform to promote the autistic cause.
"Running brings to the fore such an amazing variety of characters. During those 12 months I met everyone from the running legend Ron Hill and round-the-world sailor Dee Caffari, to Mick and his severely disabled son Phil Curry from Stratford-upon-Avon, with dad pushing son in a wheelchair, Abdifatah Dhuhulow, a disabled runner who lost his leg during the civil war in Somalia, to Boykie the loveable Golden Labrador who ran with me in a Cani-X race over Salisbury Plain.
"I had a blast. I met so many wonderful people, visited some absolute stunning places and had some fantastic runs. For me, this was the most worthwhile thing I have done in my life."
