Quick update: I've pretty much quit marathon training.
Last year, a friend from my Master's program came to this realization: "To succeed at grad school, I have to fail at everything else in life."
While sad, I've found this to be absolutely true - especially in these last three months before finishing up. Why did I decide to try and train for a marathon at the same time as completing my grad degree? Because I'm stupid, that's why.
So, no. No more running right now. I don't have time. It's not an excuse. It's just the way life is at the moment. C'est la friggin' vie.
I don't know if this means whether number 5 in May is a complete bust. At this point, nothing is certain. Will update again when I can.
P.S. If you don't hear from me, just assume I've suffocated under the soul-crushing weight of my thesis.
