To central city workers who stroll up them once a day they're gentle inclines, but Auckland's rolling slopes became topographical nightmares for the world's best triathletes yesterday.
As suspected, Auckland's hilly and technical 40km bike leg sorted the strong from the not-quite-as-strong, reducing the final run leg from a race to a coronation for New Zealanders Andrea Hewitt and Kris Gemmell.
That will please the purists who believe the bike leg has become a procession, with flat courses and drafting meaning nobody is prepared to take a gamble.
It might not please the sports bosses quite so much, who no doubt want to lure broadcasters with the promise of athletes racing each other down the chute for medals.
This was a course tailormade for New Zealand's renowned strength athletes. "I honest to god think it's one of the best courses out there," said Bevan Docherty, second behind Gemmell in a Kiwi quinella.
