KEY POINTS:
Runners of all abilities have the chance of free entry to October's Auckland Marathon or associated half and quarter marathons or 5km fun run/walk.
ChildFund will give free entry to any participant who raises a minimum of $500 (full/half marathon) or $200 (quarter marathon/5km) sponsorship.
It is modelled on an initiative at the London Marathon in which entrants have raised more than $500 million for worthy events in the past 25 years.
