Grand Palace pre-dawn start — golden temples in the dark.
Because the streets themselves have carried footsteps for centuries — you are joining a very long relay, not starting a new one.
Humidity teaches — start slow, stay slow, finish present.
A gentle profile — the course rewards patience rather than power.
Kind shoulder-season conditions — mild mornings, arm-sleeves off by kilometre eight for most runners.
A warm regional start — clubs in matching kit, coffee vans, a local mayor with a microphone. Human-scale and unhurried.
Steady, generous local support along the main boulevards and finish straight; genuine strangers-turned-friends handing out orange slices in the suburbs.
A quieter stretch usually opens up between km 17 and km 23 — an interior mile to return to yourself before the final push.
Sealed city tarmac — closed to traffic on race day
The official road is fully sealed and step-free on race day. Handcyclists routinely start with the elite wave; strollers welcome in the shakeout events.
