Keirsten won this year's All-Female Fear Factor competition. We talked to her about her fearless girl power!

Have you always been a competitive person?
Yes I've always been a competitive person. It all started with beating my younger sister Jessica at living room floor wrestling matches. Until she grew to 5'9" and kicked my butt. Then I wasn't so interested in sister cat fights.

When did you find out you'd be on an all-female Fear Factor? Did you think that was a plus or a minus?
I found out I would be on the all female Fear Factor when I showed up in the hotel lobby lounge and there was more perfume and glitter than luggage.

What did you think of the other women? Who seemed like your biggest competitor and why?
I thought all the other women looked very pretty and seemed very nice. I was a bit apprehensive about Lisa. She seemed like she could eat me for dinner if she wanted to.

What was the toughest part about the first stunt (helicopter dunk)?
The toughest part about the helicopter dunk was that the flags were all clumped in two or three places under water. The immersion wasn't long enough to get your bearings on where they were and start paddling towards them.

Was the worst tasting item on day two?
The worst tasting items were all of the mammal organs. They tasted like blood and smelled like urine. Hmmmm. I wonder how vigorous the Fear Factor Meat Team is in cleaning the body parts....

Was your strategy on that second stunt to only go for the denser/heavier items and skip the light ones (like the worms)?
My strategy on the second stunt was definitely to go for the heavier items.

Do you think going last on day three gave you an advantage?
Yes and no. I could watch the other girls and know what time I had to beat. But the wind kicked up a lot as the day went on. The hardest part of the human hamster wheel was that the wheel had black and yellow stickers on the inside that spun and made you dizzy, the ocean current underneath was coming in at another distracting angle, the whirring of the motor made the horizon jiggle and vibrate, and the wind made the entire contraption swing sideways as you ran. There was no place to look at and focus for balance. It was all feel of your body connecting with the wheel moving underneath you.

For the final stunt, do you think your ballet training came in handy as far as balance?
No my ballet training wasn't as helpful as I hoped for the balance. In ballet and gymnastics you balance on still surfaces while your body moves. This was a moving surface and I was moving too. I do think my ten-plus years as a gymnast on the balance beam were helpful in regards to the size of the wheel below my feet. I also think my experience surfing and skateboarding helped me with getting the feeling of balance on an unstable surface.

What kept going through your mind during the final stunt?
"Do it." I had no space in my head for anyone winning but me.

What's the first thing you'll do with the $50,000?
I think I will invest it in a small little one-bedroom house south of San Francisco near the water. So that I can continue to learn how to surf.
