Andrew Lemoncello gets some advice from Dan Robinson ahead of his first marathon
Britain's top marathon runner, Dan Robinson, has changed his mind and decided to run in London on Sunday.
Robinson, 35 from Nailsworth, could now run in three marathons in 2010, with the European Championships and Commonwealth Games coming up.
"How many more opportunities am I going to get to run a fast time on a London course?" he told BBC Gloucestershire.
"It'd be nice to get into the two hour 12's again and consolidate my position in the team for the Europeans."
As well as the European Championships in Barcelona in July, Robinson is targeting the Commonwealth Games in Delhi in October, four years after he won the bronze medal in Melbourne.
It means a heavier schedule than usual, but Robinson ran three marathons in 2008, finishing 13th in London and 24th at the Beijing Olympics.
"It is a tough call, it is do-able, but I don't think it's do-able every year," he said.
"As a one-off or every other year you can do three in a year.
"There's going to be a point where I might start slowing up, it might be in six months, it might be in two or three years," Robinson continued.
"I feel I'm improving still, so whilst I am I'm going to keep going and of course there's 2012 on the horizon as well so there's lots to keep going for."
The other Brit to watch in the event is Scotland's Andrew Lemoncello, 28, a former steeplechaser making his debut over the marathon distance.

Hussein Kipkemboi believes the men's world record will be broken in Sunday's race.
The current mark of two hours three minutes 59 seconds was set by Ethiopian Haile Gebrselassie in Berlin in September 2008.
"I can comfortably predict a world record in this race," Hussein said. "This is the best field in the history of the London Marathon."
Hussein, 52, became the first African to win the New York Marathon in 1987 before going on to triumph in the Boston race in 1988, 1991 and 1992.
