Oh goody, another extra long week! 
Sprint intervals x 9. Hadn't done any speedwork in forever, and I'm still not acclimated to the heat. I won't even say the temperature and humidity, since nothing starts a p*ssing contest on this board like "my weather is worse than your weather" or "my hills are worse than your hills."*
I'll just say that I'm totally not acclimated to it yet, we've really had very little opportunity to acclimate here, and when I was done with the workout (including a .8-mile recovery jog at a 12 minute pace), I took more than 15 minutes to meander back along my half-mile of lane, picking and eating raspberries, and my heart rate would not go below 135. That's how humid it felt.
I was thinking about doing this five-mile race a week from today. Not so sure about it now. 
*but I'll just mention that without ANY prompting, one of the long-time riders in our club - a 72-year-old who last year did the Continental Divide, unsupported, with one other guy, and who's ridden road bikes extensively in both the Rockies and the Appalachians - said over breakfast that without question, the Appalachians are more difficult to ride.
