Ingrid Klimke trained Damon Hill to GP before he was bought for her student, Helen Langehanenberg, who was in the top 6 individually at the London Olympics, if memory serves.
Ingrid also completes Dresden Mann at GP. I posted their video back on pg 7, I think. Not to mention team Gold and individual silver in eventing in London.
Like father, like daughter indeed :) Its a shame her brother Michael stopped competing.
