For every woman who feels like she's had to scale back her personal ambitions since becoming a mother, gold medal cyclist Kristin Armstrong has a message: Don't give up on your dreams. She retired after winning gold in Beijing to start a family; son Lucas arrived in 2010, but then she decided to compete again in the London Olympics. She won a gold medal at last.

"At the beginning I felt selfish, I felt like, 'Well, I'm not supposed to be thinking of myself anymore. It's all supposed to be for my kid.'" She faced physical challenges of getting back into competition shape after giving birth, as well. When she started racing in the spring of 2011, she was still breast-feeding; she would nurse her son, then race, then breast-feed again after the race. Her days revolved around Lucas and training.

For example, don't expect a neat home--her husband, Joe Savola, who she describes as her support system and her "protector", says he's had to give up on trying to keep everything orderly at home and just accept that their living room has become Lucas's playroom. For Armstrong, she's sacrificed time with friends who had kids around the same age--there just wasn't time. Now, she says, "That sounds like fun to me." As she heads home to Boise, Idaho, she's ready to do regular mom stuff. It was difficult for Armstrong to make the decision to participate in the London Olympics because she  _   .
