Canada's Olympic dressage team is no more after the elimination of David Marcus and Chrevi's Capital in the Grand Prix test, the opening competition for the discipline at the Olympic Games of London 2012. Competing during a heavy downpour of rain, Marcus, 31, of Campbellville, Ontario, was mid-way through his test when Chrevi's Capital spooked and went off course.  Marcus was not able to regain his horse's attention within the 10 seconds allowed under the rules, and was eliminated from competition by the head of the ground jury, Stephen Clarke of Great Britain. "He was trying so hard in the first half of the test but, at that moment, something triggered him," Marcus said. "I am not sure if it was the camera in the corner swiveling to see him, or the umbrellas, or the amount of rain he was dealing with. He just got scared, ultimately. I don't know what I could have done differently. I don't blame him at all. It is just an unfortunate circumstance," Marcus said. "Anyone who is involved with horses has gone through something like this in their career. It is just unfortunate that it was here at the Olympics.  I feel terrible for Canada, for my team, and for everyone who has been so supportive of me.  This is life with horses, and we can put it all in perspective by knowing that both Capital and I are going home healthy.  He is going to have a long career in front of him."
