Tower Bridge and back, unhurried.
Photo · London MarathonCity, flat, riverine.
From Greenwich Park past Cutty Sark, Tower Bridge and the Embankment to The Mall — since 1981, a joyful people's race.
Because the streets themselves have carried footsteps for centuries — you are joining a very long relay, not starting a new one.
The Thames does the pacing; keep the crown of the head light and let the crowd sound wash rather than lift.
A rolling profile — mid-race climbs ask for shorter strides, not harder efforts.
Kind shoulder-season conditions — mild mornings, arm-sleeves off by kilometre eight for most runners.
A Major start line: elite corrals, live broadcast helicopters overhead, a hundred thousand hearts syncing. Arrive early, breathe long, let the noise be weather rather than pressure.
World-class crowd support — dense from start to finish, with famous cheer corners that will lift you when the legs won't.
Water sections between km 18 and km 24 thin the crowd — breathe long, let the current pace you.
Sealed city tarmac — closed to traffic on race day
Rolling road profile — handcycles handle it with pacing help. Suitable for sturdy strollers on the flatter first and last thirds; expect a couple of longer gradients in the middle.
Green Park stretch and a long walk along the South Bank.
