After becoming the only cyclist – male or female – to win three consecutive golds in the same discipline, Armstrong, who turns 43 Thursday, said she hopes to inspire other moms.
Focus is always important in a time trial, but on Thursday, it was as much about survival as success: While yesterday's sunny weather would have been ideal for a ride, conditions turned nasty overnight, with a soaking rain forcing Armstrong and the other riders – who start time trials at intervals and ride without any teammates – to deal with slippery road conditions on a hilly, technical course.
She was close to the lead throughout — but she said she found another burst of energy toward the end, when her coach radioed to tell her, "You're in the medals.
Armstrong and her family live in Idaho, where she works at a hospital and trains when she finds time to ride her bike.
She was allowed to cut her hours down to 16 hours a week last fall, she said, so her family's health insurance would remain in effect while she trained for the Rio Summer Games.
