I was in a mountain biking accident and broke my sternum about three months before my unit was supposed to deploy to Iraq, and it's such a close-knit community that the idea of not getting to go is hugely jarring, so I tried to get put back in training and wound up injuring it worse.

A lot of the biking sequences in the beginning, like going down the steps and over the ramp, I of course didn't do any of that stuff. I wish I could have but I didn't.

As a kid, I did some running but especially loved biking and swimming. I grew up on Long Island, and our mom took us all the time to the ocean, so I grew up doing open-water swimming in the Atlantic.

I love England though; I've been back a few times and just love it. My favorite thing to do there is going to museums and all the castles. Oh, and my husband and I went mountain biking across England on our honeymoon!

I wouldn't recommend people to go up and ride their road bikes in Kenya. Bikes are not meant to be on the roads. But the mountain biking is fantastic. You can go right up into the tea and coffee plantations up in the highlands. You can descend the great Rift Valley.
