Well, I had to skip the Hole Half

I look forward to this race every year—a chill fall half marathon at the base of the Tetons is usually a great way to close out my season before winter sets in, but at this moment the AQI in Jackson Hole is 235, firmly in the “very unhealthy” range. Instead, I’m reading a study on the impact of air pollution on running performance to reassure myself I made the right decision.
