I managed to finish Solvang. It was an interesting contrast of tailwinds on the outbound route (average speed of 23.7 mph to the second rest stop at about mile 86, and the first hundred miles in 4 hours 14 minutes), and headwinds on the inbound route from lunch to the finish. I made the mistake of missing a traffic light on the way to Guadalupe and watched the lead group get 3 minutes on me before the light changed. Oh well - I did the last 65 miles solo and lost a bunch of time to them in the strong headwinds. Such is life!
Going UP the gradual climb towards Morro Bay at 31mph was priceless - Worth the entry fee for just that experience!
