[IZ] Morning Bike, 6/28

Through the Presidio and home across Crissy Field.

I'm still sick.

Also, about 5min into the ride I discovered that my 'puter was set to the wrong wheel circumference. It was set for bike #2, which was 2055mm instead of 2115mm (why it has settings for 2 bikes I don't know; it's not like anyone would ever move it from bike to bike). I tried to fix the setting but ended up resetting all the data instead. So, no times or distance for this ride, and the last few rides may have underestimated the distance by 3% or so.
