Olympic gold medalists work hard. They put in countless hours, make intense sacrifices, and conquer mind-boggling obstacles in pursuit of their respective sport's highest honor. When you consider that American cyclist Kristin Armstrong was able to train while being a mom-- well, it's simply amazing.

The 38 year-old Idahoan cyclist won the Olympic time trials with a time of 37 minutes, 34.82 seconds (she traveled 18 miles!). To gague just how dominant she was, consider that the second place finisher-- Judith Arndt of Germany-- finished a full 15 seconds later. When asked about her mindset, the newly crowned champion said "My mantra was, 'You have to live with this ride." She went on to add that "You're only as good as your last result."

Despite what many people might think, Kristin is NOT related, or married to, famous cyclist Lance Armstrong. Kristin is married to husband Joe Savola, and pictured above is their 1-and-a-half year-old son, Lucas William Savola. It might be a fairly safe bet that young Lucas will grow up to be a stellar athlete himself some day.

In winning her gold medal, Kristin became the oldest rider to win an Olympic time trial. She is an inspiration to cyclists, Americans, and most importantly: moms. She is living proof that if you put your mind to something and work hard enough that you can truly do anything. Way to go, Kristin.
