Update.

How to recap the past few months.

During training for the Ogden half, managed to overtrain somewhat, then caught the spring flu from my kid.

Made it to the start line with a brand-new inhaler.  Coughed two minutes before the start; threw out back.

Ran ("ran") the race anyway.  It was 40 degrees, and rainy, and miserable, but I'm glad I managed to get to run down the canyon; the race is usually sold out so it's no guarantee I'll get to do it next year!

Took a week off; returned to building a base.  Became more and more tired.  Still wheezy.

Appear to have developed anemia, and more worryingly, asthma.  Working with docs for a solution.

TL;DR: this sub-2 is going to be harder than I thought.
