Also watching the downhill was Ngongotaha's Ewen Aldridge.

It was pumping over at the Kidsworx, with plenty of locals and their families taking advantage of the free entry.
Kidsworx activities manager Marcello Ojerio said he was blown away by the sheer number of people that had come to the Kidsworx arena.
"It's really important to have a space for kids and their families. Today is good vibes."
Fans from around New Zealand and overseas were also enjoying the day.

Tyler said it was cool to be there and his favourite event was the downhill racing.
Over from Sydney, Darren Beecroft was watching his 22-year-old daughter training for the Rotorua Pump Track Challenge.
"We came over last year [to Crankworx 2016] and will be here till Saturday. It's an awesome event. It's good to see the schools' events, getting kids into mountain biking."
UK professional athlete Ben Deakin, 31, will race in the Air DH (downhill).
The racing for his event was postponed till tomorrow , which he said he didn't mind too much as it meant he could stay a little longer in Queenstown.

Deakin said he'd had a great time so far, despite it not being the best weather.
