There was plenty of support for the riders in the opening races of the world championships in this cycle-centric city where 60 per cent of the population ride bikes, most of them as their primary means of daily transport.
It's Christie's only ride of the championships and he will now return home after enjoying a strong season in Europe.
He rode for the Chinese-owned Marco Polo Cycling team along with Timaru's Marc Ryan, as well as riding with the BikeNZ under-23 team and backing Julian Dean at the London Olympic Test event where he was the leading Kiwi.
Williams finished sixth in the 13.9km junior women's time trial to continue a strong season.
The Auckland rider won silver in the individual pursuit and was fourth in the team pursuit at the recent junior track world championships in Moscow.
The teenager started strongly to be fifth fastest through the 6.7km time check, 12 seconds off the top-ranked rider, but slowed over the second half of the 13.9km circuit to clock 20:02.58, which was 34 seconds behind winner Jessica Allen (Australia).
Tomorrow Linda Villumsen is in action in the elite women's time trial, while James Oram and Fraser Gough will compete in the junior men's time trial.
