Starting from scratch
I was on the mend this week, following a recurrence of whatever my lung problem was.
I've been given a peak flow meter to measure my lung output. It's not complicated - you blow in a tube, and it measures your peak output in liters/minute.
Peak flow varies as a function of gender, height, and age. If you want to figure out what yours should be, there's a chart that allows you to do so.
For my age and height, the normal peak flow should be 570.
When I first tested my peak flow a week ago, it was 360.
Over the week, I have done the measurement in the morning and evening. If you have untreated asthma, these values will be considerably lower in the morning than in the evening.
It's too early to discern this pattern for me at the moment, but my values have been bouncing around in the 400s this week, despite me feeling O.K. So, I haven't fully recovered from whatever I had.
This has been my week:
Mon: run 2 miles. A dog licked me at my turn-around point.
Weds: swim 800m at lunch, run 3 miles on track after work
Fri: run 4 miles
Sun: run 5 miles in the hills with friends
So, I'm starting again. No races. It felt great to be on the track earlier this week, with a late-August cool breeze, and a few leaves clattering across the lanes.
Earlier this month we were in Arches national park, and I took a photo of the petrified sand dunes. I really wanted to walk out and follow the dunes as far as they went.
