It's been a rough week. Last weekend I could barely finish my five-mile Saturday (and I used to say I don't get hangovers...), and this week was unbearably hot. I ran a 24:11 5K on Tuesday in 90-something degrees with high humidity. Wednesday was cooler but not much better—I took it easy and finished in 24:40.
Today, though, today was great. I ran hard but I felt great the whole time because it was nice and fresco outside, and I ended up finishing 3.1 miles in 21:40, my best time ever.
