Abby joined us this time so we headed to the San Luis Rey River Trail, a 9-mile paved road that runs along the San Luis Rey River in Oceanside. Since we knew we'd have to go the same distance back, we started at the 3-mile mark and headed west towards the beach. We pedaled along the beach, then through the harbor. I think in the end it was about 15-miles which was about the right distance for Abby. Her butt started to hurt towards the end but I think she had fun and will join us for the next one.
