Pippa Funnell is the recognised champion of the eventing world. She began riding when she was very young - on a pony lent to her by a friend of her mother's. An Olympic champion, she became the first and currently only person to win eventing's greatest prize, the Rolex Grand Slam. Tilly's Pony Tails mark her debut in children's fiction. She lives in Surrey with her husband, William Funnell, a top class show jumper.
