Step 1: Ride from my mother's house in San Juan to PCH, using that handy creek trail (about 20 minutes).
Step 2: Pay $1.25 each to ride the OCTA 1 up PCH to Long Beach (about 1.5 hours).
Step 3: Ride from 7th and PCH in Long Beach to any Blue Line Station (I can't estimate the time here cause we stopped at La Palapa Michoacana for the best tacos in Long Beach, and then at Portfolio for coffee).
Step 4: Pay $1.25 each to take the Blue Line to Pico station (50 minutes).
Step 5: Ride to Bobby's cousin's house in Miracle Mile. Olympic is not busy on Sundays, it turns out, so we had a lovely ride along that thoroughfare. It's a bike route, too (50 minutes).
That's quite a long time (about three hours) to travel about 76 miles, but we only paid $5 for the privilege. On Amtrak we would have paid upwards of $16 each.
