Turned out I'd partially torn my Achilles tendon while messing around with Kekai, swimming through an undersea arch in July 2016. I'd kicked a coral head above my head (didn't realize I'd floated up so high). It hurt enough that I put off the start of marathon training until August, but at that point decided that I'd better just run through it (it only really hurt for the first 3 miles plus while running up the crater walls); lots of ice and I was fine. Saw the Dr. the week after the race and he decided that if I'd been able to train for a marathon on it, it couldn't really be that bad. At the beginning of this month, they finally sent me to an orthopedist who had me immobilized in a cast within 15 minutes of walking in her door.
