This is my "second" time crossing the country (the first was riding from Chicago to Seattle so not exactly crossing). I flew from Santa Barbara to Seattle, built the bike in the airport, slept at an airport motel for the night, rode up to Blaine the next day then came down the entire way to the Mexican border along mostly the Pacific Coast Highway.
Going to Blaine from Seattle took 1 day, so I was actually on the road for 16 days and did 1,823 miles (2,934 km), averaging about 114 miles (183 km) each day. The longest day was 163 miles (262 km) going from Blaine to Shelton, the longest ride was 253 miles (407 km) going from Santa Barbara to the Mexican border, and the shortest day was 32 miles (51 km). Over 100 miles (161 km) a day is an awkward pace as it really sucks all the fun out of touring and yet it's nothing that competitive (I spent more than 2x the fastest known time). The fun and chill pace is probably 3-5 hours of moving time a day but I had to do this due to time and budget constraints.
This trip didn't happen around the best time as during my first day Warmshowers went down (and went back up right when I started my final ride) and a timber fire caused Highway 1 to close around Big Sur, but I am still really happy that I accomplished it - type 2 fun as people call it.
I spent 7 nights at campgrounds, 6 nights at motels (including the night in SeaTac), 1 night at a friend's house and 1 night at home in Santa Barbara - I am not rich, I am just a graduate student who borderline cannot afford the city... I got chased by a dog once, got brushed by a pickup truck once, met numerous riders doing different parts of the PCH and one guy doing the Pan-American Highway. The itinerary that I took:
Day 0: SeaTac to Blaine, 133 mi/215 km, Birch Bay Campground
Day 1: Blaine to Shelton, 163 mi/262 km, motel
Day 2: Shelton to Astoria, 129 mi/208 km, Fort Stevens Campground
Day 3: Astoria to Newport, 130 mi/210 km, motel
Day 4: Newport to Coos Bay, 107 mi/173 km, Sunset Bay Campground
Day 5: Coos Bay to Crescent City, 134 mi/216 km, motel
Day 6: Crescent City to Eureka, 83 mi/134 km, motel
Day 7: Eureka to Leggett, 88 mi/142 km, Rock Creek Campground
Day 8: Leggett to Gualala, 106 mi/170 km, Gualala Point Campground
Day 9: Gualala to Creekside Loop Campground, 87 mi/140 km
Day 10: Creekside Loop Campground to San Francisco, 32 mi/52 km, hosted by friend
Day 11: San Francisco to Monterey, 121 mi/195 km, Veterans Memorial Park Campground
Day 12: Monterey to Paso Robles, 120 mi/193 km, motel. I did this ride on Aug. 23 and technically Highway 1 was open momentarily amid the burning fire from Aug. 22 to Aug. 27 but I missed it... probably wouldn't have been a good idea to go through anyway, this is not saying riding inland to Paso Robles was anything enjoyable...
Day 13: Paso Robles to Santa Barbara, 131 mi/212 km, home
Day 14 & 15: Santa Barbara to San Diego/Mexican border, 253 mi/407 km. I started this ride at around 5:30pm on Aug. 25, went through LA and Orange County at night and arrived at the border at around 2pm the next day, then I caught the 4pm Amtrak train back to Santa Barbara.
Regarding the gears that I used, I have a titanium bike with aerobars, a 7 liter backpack with a 2.5 liter reservoir, multiple frame bags, one-person tent and sleeping bag, two sets of kit, two 10,000 mah power banks, an electric pump (and a backup hand pump), among other things.
Feel free to ask me anything about the trip and feel free to connect with me if you also want to do long-distance stuff around California!
