Who is planning on doing this event? I did the 60 miler last year and it was fun but would have liked to have ridden with more of the NC3 gang. This year I'm doing the 98 mile route.
Here's the website link[https://www.sdgranfondo.com/] for more info.
Also, if you also belong to Swami's, Tom Kattus from Campagnolo is offering Swamis a 20% discount to Campanolo Gran Fondo, San Diego. Unfortunately this is for New registrations only. Enter code KATTUS20 for a 20% discount.
