Douro half.
River, coastal, rolling.
Douro river valley into Foz do Douro's Atlantic mouth.
Because moving beside water borrows its willingness; the current does part of the pacing for you.
Bridges, port cellars, ocean — a wine-country cadence.
A physical profile — respect the ascents; let the descents restore the breath.
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.
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.
Sunset at Foz, still.
