Great Eastern Women's Run: A 0.1km Dash Alongside a Half Marathon
The Great Eastern Women's Run in Singapore includes a genuine 0.1km "dash" distance alongside its half-marathon and 2km/5km/10km options -- about as short a distance as any race in the region's calendar offers, explicitly designed to be completable by a very young child or a complete first-timer.
Pairing that with a serious half-marathon distance at the same event means a mother chasing a real half-marathon time and a young daughter doing her first-ever timed run can both cross the same finish line on the same morning.
The National MILO Marathon's 1km Option
The National MILO Marathon includes a 1km distance across its multiple Philippine city legs -- short enough for most children to complete comfortably on foot, while parents or older siblings attempt the 10K or half marathon at the same venue.
Because this format repeats across several city legs (see this site's guide to Southeast Asia's race series), a family based in more than one part of the Philippines has more than one chance a year to find this exact distance option nearby.
Vietnam's Techcombank Races: A 1.5km Family Option
Both the Techcombank Ho Chi Minh City International Marathon and the Techcombank Hanoi International Marathon include a 1.5km distance alongside their full six-distance spread, and the Standard Chartered Hanoi Marathon Heritage Race offers a similar 2.1km option -- genuinely short distances built into two of the country's biggest, most established race brands rather than only offered at smaller local events.
This matters specifically for a family that wants the full-scale, well-organized flagship-race experience (aid stations, medal, festival atmosphere) without needing every family member to attempt a serious distance to get it.
AIA Rock 'n' Roll Manila's 1km Option, at Night
The AIA Rock 'n' Roll Running Series Manila includes a 1km option within its night-race, multi-distance format -- a genuinely different family race-day experience from the region's usual pre-dawn start, since a night event doesn't require getting a young child up at 2am to participate.
For a family specifically put off by the region's typical early-morning race culture, this is one of the few short-distance options that sidesteps that particular obstacle entirely.
