The competition replaced the
IAAF Grand Prix Final, which had a varying set of events each year, with a full set programme of 33
track and field events. The year's top seven athletes, based on their IAAF World Rankings, qualified to compete in each event, with an extra four athletes selected for races of 1500 metres and above. One additional athlete, a
wildcard, was allocated to each event by the
IAAF and replacement athletes were admitted to replace the qualified athletes that could not attend the final.[2]
