London Marathon: Scott Overall plots London 2012 campaign
By Mike HensonBBC Sport
When Scott Overall lines up alongside the world's best marathon runners on the London 2012 startline it will only be the second time he has raced 26.2 miles.
Indeed, a year ago the Londoner talked, rather than ran, marathons.
The 29-year-old used to advise weekend plodders and joggers as part of his job in a running shop in south London.
That came to an end in September when he ran two hours 10 minutes and 55 seconds on his marathon debut in Berlin to become the first, and so far only, man selected for Great Britain's athletics team for the London Games.
This week Overall has been dispensing advice to amateurs again as he prepares for the London Marathon on Sunday.

Unlike them though he is not concerned about completing the course, knowing that his pace-making duties will be done and dusted around the 18-mile mark.
"I am going to run the London Marathon one year so it enables me to learn the course and get to know the procedures without actually having to race it," he told BBC Sport.
"This year gives me a chance to practise the drinks. The only time I have run and taken on board fluid was at Berlin's marathon.
"And if I can help some of the other British guys do the qualifying time then that will be good as well."
To run the full distance only once before the Olympics may seem a relaxed approach, but the marathon is not a casual event and Overall is not a casual athlete.
His initial aim was to represent Great Britain on the track, as he did at the 2005 under-23 European Championships and 2010 World Indoors.
However, London Marathon race director Dave Bedford persuaded him to try the longer discipline and was proved right as Overall won his place at London 2012 with more than seven months to go.
"Obviously you can't run marathons repeatedly," explains Overall.
"A lot of the the British guys are doing a marathon now around the end of April to qualify because they have not yet run the qualifying time.
"If you do that, you are squeezing everything in because you will take a few weeks off to recover and then you would ramp straight back up for the Olympics.
"Being selected early has allowed me more time to focus on training rather than chasing qualifying times."
It is a luxury that has not been afforded to some of the favourites.
Scott Overall's marathon training
"At the moment my training is not as intensive as if I was running the full distance. I am running 90-100 miles a week, just ticking over and staying in shape. But after the London Marathon I'm going out to Flagstaff, Arizona to turn the focus to the Olympic marathon. I will reach 120-125 miles a week out there. On Sundays I do my long run, around 20 or 21 miles, and the furtherest I'll go is 24 miles which I'll do a couple of times before the marathon. Tuesday is a faster-than-race-pace session, perhaps 9-12 miles, and then on Friday I do a longer tempo run. That starts off slower than race pace and builds speed over somewhere between 10 and 18 miles."
Geoffrey Mutai won last year's Boston and New York marathons, clocking the fastest time ever en route.
