Right, D-Day: the fourth, longest and final distance of this little competition, 5 kilometers. I have to run sub-24 to keep my position, my PB is 24:17, a little over a year ago, and based on what I've done in the past one and a half month (faster times than I'd ever imagined on 500m, 1500m, 3k and 10k) I know I can and probably 'have to' set a pretty strong new PB, but boy...is it gonna hurt. I'm expecting pretty much the toughest battle of all distances, especially mentally, where the bad humidity today isn't going to help. Time to play Jens Voigt on a loop in my mind.
