The 500th Pegasus parkrun will be held on Saturday, August 29.

The first Pegasus parkrun was held 10 years ago on June 18, 2016, with 61 finishers and six volunteers.

The organisers of the popular Saturday morning fun run and walk around the Pegasus Lake are going blue to commemorate their 500th event.

They are inviting everyone who has ever attended the runs, or anyone interested in taking part, to assemble by 7.50am on Saturday dressed in blue as they try to eclipse the record they set at their 400th event which attracted 716 finishers and 34 volunteers.

Parkruns are a free, community event where participants can either walk, jog, run, volunteer or spectate.

New Zealand presently has 75 parkruns in towns and cities nationwide.

Each parkrun is five kilometres long and takes place every Saturday morning.

They are positive, welcoming and inclusive as there is no time limit and no one finishes last.

Everyone, including controlled dogs on leashes, are welcome to take part.

Parkruns began in the United Kingdom in 2004 and nationally nearly 20,000 events have been held since they were first introduced in New Zealand in 2012, with over two million finishers.
