Sydney has a few major running festivals every year, including one full marathon that traces the streets of the city over Sydney Harbour Bridge and through Centennial Park. For events of a more manageable distance, there are regular 5K, 10K and half marathons that take place every season. There's courses suitable for kids and families, and funds raised by most events go towards charitable organisations around the country.
Start training at these free outdoor gyms in Sydney or scenic running routes. Or plan the ultimate chill out session, post-marathon, at these yoga retreats in NSW.
