Did the Lighthouse 100K on the tandem. Perfect weather and the new course starts in Morro Bay which is an improvement. We paid the tariff so we hit every rest stop. Even though this is a pretty flat course, 15.9 mph moving average is still good for us old folk. http://app.strava.com/activities/23536696

This is definitely a good first 100K, or a good first Century if one is doing the easy version. I've never seen RidewithGPS and my Garmin 800 come up with such a big discrepancy in elevation gain: 2200' for the Garmin, 3700' RidewithGPS - go figure.
