As 56,000+ runners prepare to take on the 2026 London Marathon on Sunday 26th April, our latest analysis of London property prices along the marathon route reveals a interesting story: the average sold price between the starting line in Blackheath and the finish line on The Mall differs by almost £1.4 million. We've mapped sold price data from the Land Registry against all 26 mile markers to show exactly how London house prices shift mile-by-mile across the capital. It's useful context whether you're cheering on a runner, considering a move, or simply curious about how property values change across SE3, SE8, SE18, E1 and SW1A. Here's what the route reveals about the London housing market in 2026.
How much do homes cost at the London Marathon starting line?
The 46th London Marathon is set to take place on Sunday 26th April 2026, with the 26.2-mile course winding through 15 different London postcodes, and the price of a home shifts dramatically from one mile marker to the next.
Blackheath's SE3 postcode is home to the start line and the first mile marker. Over the last year, the average home in SE3 has sold for £550,000, offering runners and spectators a relatively accessible entry point into the London market before the route heads east.
Most affordable postcodes along the London Marathon route
Buyers searching for the best value vantage point on the course will need to clock a few more miles. The SE8 postcode of Deptford, which covers mile markers seven and eight, offers the most affordable property prices anywhere on the route. Over the past 12 months, the average price of homes sold across SE8 came in at just £409,000.
The SE18 postcode of Woolwich, home to mile markers two and three, takes second place with an average sold price of £425,000 over the last year.
If you'd rather buy closer to the latter stages of the race, mile markers 13 and 22 in Shadwell's E1 postcode are worth a look. Average property prices there sit at £470,000 — the third most affordable postcode on the entire marathon route.
London Marathon finish line is the capital's priciest postcode
Runners crossing the finish line on The Mall are entering some of the most expensive real estate in the country. The SW1A postcode, which covers the finish line itself, has the highest average house price anywhere on the route.
Over the past year, the average home across SW1A has sold for £1.9 million, that's almost £1.4m more than the average near the starting line, and £388,000 more expensive than at the time of the 2025 marathon.
