A view from the start gates as riders leap into action.

Scott Croxall was in brilliant form, powering his way to the men's final with ease.

With her title rivals failing to shine, Jacqueline Legere went into the women's final knowing a win would seal the world championship.

And win she did, surging clear of the other finalists to become champion for the second year in a row.

Scott Croxall knew a win would give him back the title he lost to Cameron Naasz 12 months ago.

The other riders watched on nervously in the athlete's tent.

But it was Naasz who grabbed the lead early on, while Croxall crashed heavily on the first turn.

Despite a slip himself near the end, Naasz cruised over the line to make history by becoming the first back-to-back world champion.
