KIMBERLY WALKER, 30
Profession: Founder of Saierfu, a home goods line designed in New York and sold in Shanghai, China
Obsession: Horseback riding
First show? When I was 2. My family is full of riders, so I grew up around horses.
Type of riding? Mostly jumpers, which is about height and speed.
How many horses do you own? Three. I've had about nine total.
Your stable? Winley Farm in Millbrook, New York.
How often do you ride? Most afternoons.
Routine? I take each horse out for an hour. I work them on the flat or a course, or take them to a field.
Is riding athletic? Absolutely! I sweat my butt off every day. It's rewarding because ... It's you and a 1,200-pound animal that you're trying to finesse into listening to you.
Best memory? Swimming with a Clydesdale in a pond while I was fully dressed in boots and britches! — Jessica Flint
First stop: Take lessons at a barn.
