Bridge and back.
Photo · San FranciscoCoastal, very hilly, iconic.
Crosses the Golden Gate Bridge twice — fog, headwinds, and a city that earns its miles.
Because moving beside water borrows its willingness; the current does part of the pacing for you.
Bridge fog erases pace — become breath and cadence.
A physical profile — respect the ascents; let the descents restore the breath.
Warm to hot. Early start, shade-line and salt matter — carry more water than you think you need.
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
Elevation and mixed surfaces make this a physical line. Handcycles only with a support team; sturdy adaptive strollers on the flatter opening kilometres.
