A quick park and grab in Olympiad Plaza. During the 1984 Los Angeles Olympics, Olympiad Road from La Paz Road to Marguerite Parkway was used as part of the road race (cycling) competition. In fact, the official start and finish line for the race is still in place and you can visit it yourself near the entrance to Lake Mission Viejo, just up the road. Here's a map of the original route of the Olympic event.
