Wildfires and Triathlons

The table below shows shows the air quality for Truckee, CA over the past month as measured at the Truckee Fire Station.  Why's the air quality in Truckee important?  Truckee is where I'm entered in a triathlon this weekend.  (Part of a triathlon relay, so I'm just signed up for the running leg.)  And because of all the wildfires in Northern California, there have been very high levels of "particulate matter" in the air over the past few weeks.  It's easy to see the score rise over the past month since the fires started.  A score under 50 on the chart below is considered "good," above 150 is "unhealthy," and over 200 is considered "very unhealthy."  

It also turns out that a score over 150 is considered "not good for triathlon-ing."  The race has been cancelled.  No refunds or anything.

So that kind of stinks.  But the upside is that I get to hang out in California...
