Cycling: New Zealand's Campbell Stewart claims gold medal at Track Cycling World Championships

Kiwi cyclist Campbell Stewart has stormed home to win gold in the Omnium at the Track Cycling World Champs in Poland. 

The 20-year old produced a string of consistent performances across the four-event race, culminating in a brilliant performance in the final points race. 

Equal on points with Great Britain's Ethan Hayter heading into the final showdown, Stewart endured a back and forward battle, before sprinting clear in a break and lapping the field to gain a bonus 20 points. 

That allowed him to cruise to his first rainbow jersey, and New Zealand's first gold medal of the event.  

"I can't believe it," said Stewart immediately post-race. "It's awesome. To be able to get up there and mix it with the big guys and come away with that, it's just unreal."

"I always had to keep myself up the front with everyone else and I guess it just pays because you can kind of keep an even amount of work throughout the day. At the end I had to follow a bit and attack and it all worked out."

Stewart is the third Kiwi on the podium following Thomas Sexton and the women's pursuit team's bronze medal efforts.
