It's day 5 of the 8 Days of Dressage Anywhere!
Today's prize is a copy of Valegro: Champion Horse, but it's not just any copy; this one has been signed by the man himself, Carl Hester!
We love this book, telling the story of Valegro's rise to international fame. Along with Carl Hester, more than 30 other people involved share their memories and favourite moments.
It's really easy to enter the competition, just go to our Facebook Page and look for the video pinned to the top. Make sure you watch the video before midnight as we'll pick a random winner first thing tomorrow morning, 28 January!
