The average price of buying a property along the London Marathon route has been revealed as this year’s runners prepare for Sunday’s race.

The 26.2 mile route begins in south-east London before snaking through Canary Wharf and The City and ends at The Mall.

House prices in Blackheath, the first mile marker, dropped 16 per cent year-on-year to £510,432 on average, according to estate agent Benham and Reeves.

However, prices in nearby Deptford, where runners will reach eight miles, soared 18 per cent to £532.350.

Property prices in Monument and Blackfriars both jumped nine per cent, to £1.6m and £682,500 respectively.

The last few miles of the race go through the most expensive property areas, as the average property price in Embankment and St James’s Park was £1.74m and £1.69m.

“There’s no better way to showcase the diversity of the London property market than the London Marathon, with the route passing through some of the capital’s most notable areas, Benham and Reeves director Marc von Grundherr said.

“Unfortunately, the capital’s homeowners will be forgiven for being less jubilant than those crossing the finish line with price growth declining year on year across the capital. However, some areas continue to show good stamina and have registered positive movement despite wider influences.

“Hopefully, by the time the next London Marathon rolls around, a greater degree of market stability will have returned, and we will be seeing positive price growth the length and breadth of the course.”
