For every woman who feels like she’s had to give up her personal ambitions since becoming a mother, gold medal cyclist Kristin Armstrong has a message: Don’t give up on your dreams. She retired to start a family after winning a gold medal. Her son Lucas arrived in 2010, but then she decided she wanted to compete again in the Olympics. The decision to start training again wasn’t easy. “I struggled with that a lot,” she told a newspaper. “At the beginning I felt selfish. I felt like, well, I’m not supposed to be thinking of myself anymore, and 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 next year, 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. “I feel like I’m able to do what I love to do and still manage a family and have that balance,” Armstrong said. “That you have a family or a child doesn’t mean that you have to stop going after what you dream of.” However, it doesn’t look that easy. She points out that we can’t have it all without making some sacrifices. For example, don’t expect a neat home— she’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. Moreover, she’s sacrificed time with friends who had kids around the same age— there just wasn’t time.
