Chicago threw up another tough day with hot and humid conditions for the elite men at the ITU World Triathlon Series race with Ryan Sissons finishing the best of the New Zealanders in 16th place.
Sissons ran home strongly to overtake close to a dozen competitors in the final few kilometres including countryman Tony Dodds (28th) with Tom Davison withdrawing early on the run.
Spain's Javier Gomez won the race, with Portugal's Joao Pereira Portugal second and Spain's
Mario Mola third
The result leaves Sissons at 13th on the overall World Rankings, with the New Zealanders now moving on to their base in Europe to prepare for Hamburg WTS and then on to Glasgow for the Commonwealth Games at the end of July.
