Go with miles, why not? Accuracy is overrated.
I did a three at lunch. Good day for it, 70s and mostly cloudy.
I gave blood yesterday. My hemoglobin count is usually right around the
cut-off number 13. Every so often it's below 13 and I can't give. Now
yesterday it was at 16. I mention this on the running club thread because
usually I go for a jog at lunch even on donor days, and donate at around
1:00 or 1:30. But yesterday I did not have a chance to run. Hmmm.
