Running the marathon is an opportunity to see some of London's finest sights - and its real estate.
Its 26 miles weave around the east of the capital, which has had some of the highest house price growth in the city; it presents a tour of the highs and lows of London's volatile property market.
The average price of a home along the 26 miles is £732,110, according to House Simple, far higher than the London average.
In Woolwich, south-east London, where there is a huge amount of development, property increased in value 8.3pc in the last year, the highest on the route. Prices here are the lowest along the 26 miles, and it is in the process of being boosted by a huge regeneration scheme.
Blackfriars is another area where new building schemes have boosted house price growth. New skyscrapers, such as One Blackfriars, have led to the surrounding area, which features towards the end of the route, soaring in value by 7pc in the last year.
Deptford, which is on miles seven and eight of the race, recorded 6.2pc growth in the last year, partly due to its below-average price of £412,796. First-time buyers have found pockets of affordability, while artists have flocked there due to lower prices and availability of large, warehouse-style buildings.
It is where the race finishes, in the centre of the city, that has been hit by recent falls in property prices. The most expensive areas have been hit as higher levels of stamp duty mean there are fewer transactions, leading to lower asking prices.
In St James's, at the finish line, house prices have dropped 1.8pc in the last year. But this fall is far less than other expensive areas of London, such as Chelsea, where the most expensive homes have fallen in value by as much as 13pc, according to Knight Frank.
