Running 17:32 [5] 4.8 km (3:39 / km)
Last 4x1200m I intervals before leaving for COCs (log'll be quiet or at least infrequently updated until I return) in 4:20, 4:20, 4:25 and 4:27. Still cool by July DC standards so can't ascribe the slowing purely to overheating. Guess I am doing these fast enough; jury still out whether I might be doing them too fast/faster than necessary. Not like I'm doing them with competition to make me push too hard, at least.
