A record 90,000 people, from seasoned athletes to casual walkers, will lace up their running shoes to take part in the Voltaren City2Surf this Sunday, marking the second year in a row the race has sold out. The 14km course from Hyde Park to Bondi Beach has raised $59 million for charity since 2008 – a tally expected to increase by $5 million to following this year’s event. This year, the 55-year-old race also debuts a new name: the Voltaren City2Surf, part of a three-year partnership deal with the pain relief brand. With the city bracing for road closures and large crowds, here’s everything you need to know before you hit the start line.
