Great course. The finishing straight is the only section of flat. The rest is slight hills up and down, similar in grade to the hills in Ladera Ranch or Barrio Logan. Because turn 4 is off camber on the inside, the usable section of the road is really narrow. Trying to go five wide through that turn is a mistake. Final turn is less than 200 meters before the finish, and is preceded by a short downhill section, similar to Barrio Logan.
If you like the Barrio Logan course, you'll probably like San Clemente.
