She thought she needed to explore the limits of her endurance, and she suspected the exploration would be a long one. There was a JuCo with a cinder track not too far from the house. She began to drive over there in the early mornings just after Henry left for work. Henry didn’t understand the running. Jogging, sure-lots of women jogged. Keep those extra four pounds off the old fanny, keep those extra two inches off the old waistline. But Em didn’t have an extra four pounds on her backside, and besides, jogging was no longer enough. She had to run, and fast. Only fast running would do.

She parked at the track and ran until she could run no more, until her sleeveless FSU sweatshirt was dark with sweat down the front and back and she was shambling and sometimes puking with exhaustion.

Henry found out. Someone saw her there, running all by herself at eight in the morning, and told him. They had a discussion about it. The discussion escalated into a marriage-ending argument.

“It’s a hobby,” she said.

“Jodi Anderson said you ran until you fell down. She was afraid you’d had a heart attack. That’s not a hobby, Em. Not even a fetish. It’s an obsession.”

And he looked at her reproachfully. It would be a little while yet before she picked up the book and threw it at him, but that was what really tore it. That reproachful look. She could no longer stand it. Given his rather long face, it was like having a sheep in the house. I married a Dorset gray, she thought, and now it’s just baa-baa-baa, all day long.

But she tried one more time to be reasonable about something she knew in her heart had no reasonable core. There was magical thinking; there was also magical doing. Running, for instance.
