Lighter conditions cause upsets up and down the rankings on day four of the kiteboard racing worlds in China. The lighter, shifting winds that graced day four of the kiteboard racing world championships threw a spanner in the works of the reigning title holders’ virtually unchallenged bid for back-to-back victories, while favouring riders whose style more suited the conditions.

The story of the day was the assault on the leader board by nineteen-year-old Florian Gruber as he advanced his standing against Johnny Heineken who had proved all but unbeatable in the windier conditions. The order at the top of the women’s fleet was even tighter. Bridge finally halted Heineken’s winning streak in the second race of the day. But the American only faltered momentarily before reasserting her dominance.

Check out the video highlights from the fourth racing day.

Day five to conclude the event will see the top ten ranked men and women competing in platinum fleets for the final medal positions in forecast similarly light conditions.
