Bejing Olympics: Injury to Zara Phillips' horse Toytown a mystery - Olympics News - Telegraph
It's a shame that she has to pull out again. Bad luck. On the other hand, it does happen to athletes and the horse must be counted in as an athlete too. Riders don't have the usual problem of getting too old, the older the better, so there might be more chances for Zara to come. The horses are usually older too, from 8 years of age up to 15, because it takes so long to train them etc.
Maybe she'll make use of the spare time and get engaged to MT (who's busy with Rugby I believe).
