What's a Ballot vs Registration vs Qualification?
BallotRandom Draw
You apply during a fixed window and are randomly selected. Races like London, Dublin, Sydney, and Valencia use this system. There is no advantage to applying early or late within the window.
RegistrationFirst-Come, First-Served
Registration opens on a set date and places are allocated on a first-come, first-served basis until the race is full. Amsterdam, Athens, Paris, Rome, Seville, and Manchester use this model. Speed matters on opening day.
QualificationTime-Based Entry
You must run a qualifying time at an eligible race to earn your place. Boston is the most famous example. Qualifying standards vary by age and gender.
