This video ( 3 sections) is of the Big Sur Marathon.
I ran it 1989, 1990, 1992 then 1994
BUT--after the 2004 Marine Corps Marathon, I developed atrial fibrillation. Got that resolved, and started having back problems. (Legs would go numb, severe sciatic pain in rt leg) .
So, I do the gym three times a week and miss the running
