The half marathon, 21.1km, is the sweet spot of distance running: long enough to be a genuine achievement, short enough to race hard. It's the most popular serious distance in the country, with standout events like the HOKA Runaway Sydney Half through closed city streets, the Parramatta Half's rockstar stadium finish, and plenty of certified courses ideal for a PB attempt. From flat, fast city halves to scenic coastal and country routes, there's a 21.1km for every runner and almost every weekend of the year.
