For seven days, cyclists who have medaled in the Olympics and competed in the Tour de France race along California's coastline, undulating back roads, and highways as a part of the Amgen tour. On Mother's Day, guests gather to watch the race, which raises funds for cancer research and prevention. But they can do more than watch—they can boogie to live music, sample wine and chocolate truffles, and enter to win giveaways and prizes that may include signed jerseys or bicycles' autographs.
