If I had a time goal in mind, I never got to that 'cool as a cucumber' state, and how early in the week I achieved my 'oh shit' moment generally changed with the length of the race. Marathons were around Wednesday. A half might get me to Thursday. Expos also tend to intimidate me. I see a whole bunch of serious-looking runners, and I feel like a total fraud.
Run/Bonus Scenario: This happened to me today. I wanted to run 5 miles, which, depending on the day and how much walking I do, takes between 45 and 60 minutes. Literally 6 minutes into the run, the skies open up alongside loud thunder and lightening. I bailed and ran back to my house. Of course, 15 minutes later, the weather was completely clear, and I was a little annoyed at having missed the run. Enh.
Other annoying thing: It was 97+ degrees here yesterday. We turn off our AC during the day while we're at work, and when we got home, the compressor would not turn on. It got up to a pretty-hot 86 degrees on the second floor of our house. We slept on the first floor, where it was a balmy 82 with fans, but poor L was sweating the whole night and took off her diaper and t-shirt and kept waking up to ask for water
Naturally, we call our HVAC guy, who came out today to let us know that the local electrical provider disabled units to moderate demand on the energy grid. Fine thing to do, but it pissed me off that they didn't manage expectations. Hey, between the hours of 5 and 8PM, you won't be able to turn on AC. Based on a conversation we had with our AC guy last night, he recommended we shut down the unit entirely until he get there, so even when the forced disablement ended, we didn't know. In any case, we weren't charged, but it was a crappy night for all of us.
