Aussies lead eventing

However, the French team was dealt a blow with a sudden withdrawal from the Beijing Games.

By the end of the second session, the Australian eventing team had amassed a total of 102.80 penalty points, followed by the USA team with a total of 121.50 penalties. Germany's team came in third place with 135.30 points.

Dressage, the first phase of eventing, will be followed by cross-country and show jumping next week.

"I thought it was very tough. My horse is 100 percent fit and it is suitable for the course. The test is that I don't stuff it up and take a wrong line," Lucinda Fredericks (pictured) said, referring to the cross-country course.

Germany's Heinrich Romeike told reporters: "He did everything I asked. He was agile, wide awake, fully switched on. I noticed his eagerness."

Some horses spooked slightly at members of the audience who used pieces of paper to fan themselves in the hot weather.

"Of course horses notice these things. They are flight animals by nature and had to look out for wolves," German team-mate Frank Ostholt said.

France's Nicolas Touzaint announced his withdrawal from the Olympics after his horse, Galan de Sauvagere, was injured in a suspected accident in his stable in Hong Kong.

"The groom heard a bang in the stables during a thunderstorm yesterday morning. We didn't think it was serious, but when we were warming the horse up today we saw he was not well. He is injured on the hind leg," team leader Thierry

Touzaint said at a news conference late on Saturday. New Zealand's eventing team, which welcomed two-time Olympic gold medallist Mark Todd after his eight-year retirement, slipped to sixth place.

Three members out of each country's eventing team rode in the dressage on Saturday, and will be followed by the third and last session on Sunday.
