Does anyone here compete in three day events or do cross country? Does anyone want to?

I think a 3 day event is almost too extreme to take a horse on, but I would like to try cross country one day.

Hey i'm german, i start in 2 day or 1 day events :)
the dressage in the morning
the jumping 30 min. later
and the cross country in the afternoon
:] or over 2 days

my horse is seven, and i startet when it was five with cross country
last year i did eventing

have you got a special training?

(i ride 5 days a week dressage , 1 jumping and a day off )
