From the lava fields of Kona last week to the golden shores of Wollongong, Australia: it's world championship season.

This weekend Wollongong hosts the World Triathlon age-group, U23, juniors, and para world championships. Plus, a stacked WTCS Grand Final (which determins the world champion) and the re-scheduled T100 race.

World Triathlon World Title: In the WTCS series, Beth Potter and Cassandre Beaugrand are locked in a tie for the top spot going into this final race — with SuperTri champ Jeanne Lehair 200 points back in third. Katie Zaferes helps us break down the complicated points system and how the race could break up. With a “hilly-ish” 7-lap bike course, will a break stick or will it come down to the run?
