ATTA is an association of individuals who run around 30 time trial events in the Perth region every year on a range of courses, both open road and closed road, with distances ranging from about 16km to 160km. Everyone is welcome irrespective of what type of bike you have or your current ability, we have road bike categories, we have live timing at every event broken down y distance and age groups, toilet facilities at every event, a friendly atmosphere and more often than not we are either close to a local bakery or we organise a coffee van, so come along and see what ATTA is all about.

ATTA was founded in 1988 by a group of riders who saw the need for a specialist club to cater for Time Triallists in WA; they took over the running of a number of events which had been run for a number of years by the former WA Veterans Cycling Association that eventually merged with ATTA. At the time of its formation, ATTA was the only such specialist group in Australia.

We have ventured off-road, particularly during the winter months, into the realm of MTB / CX / Gravel time-trialling, but now we only have one such event a year.
