HEFFRON PARK CIRCUIT

It has been said that if you can ride this criterium circuit well you can race anywhere.  The circuit has some very tight left and right corners including the infamous "squircle". The remainder is basically flat, except for the two small pimple type risers, allowing for a good traveling speed in the big chain ring.  Whilst it might look like a good course to get away from the bunch, there is always a good breeze at Heffron so be prepared to do a LOT of work out there by yourself.  It is only the very fittest riders who can ride away from a bunch on this course.

The Start/Finish line is located just south of the carpark.  Prior to the start finish is a straight of about 400 metres allowing for a really fast sprint finish.  From the 400 metre mark (see map),  the track is labeled in decreasing 50 metre  increments.
