Run 1:16:00 [3] 15.0 km (5:04 / km)
The conditions got the better of me today. It was just as humid, if not more so, as last night (for sustained high dewpoint the current event ranks second only to one in February 1955, a record which may well fall by tomorrow morning), I hadn't slept well, and expected it to be tough going, which it was. Sluggish in the first half-hour but thought I might be able to fight my way out of it as I have a couple of times in recent weeks, but taking on water had no real effect. By 45 minutes I was starting to entertain the possibility that I might not last for two hours and readjusting my course to one with reasonable bailout options. By 60 minutes I was really struggling, and holding out to reassess at the next water point. There was no improvement after that, either, and I decided I wasn't going to achieve much by pressing on (and ran the risk of getting into real trouble; it was a definite danger sign that my pace had slowed by 20 seconds/km in the last 3k, something which never happens on a normal run).
A failed attempt at a long run (and a sleep-deprived night) probably wasn't the best of preparations for a stressful day, either...
