This morning I felt irritable, and ended up running 6 1/4 km (about 4 mi) on autopilot. Now that I've run I feel much better.
If that was 6.25 km, my pace was under 4:12/km, suggesting that I'd be okay at a race pace around 85% max. heart rate instead of over 90% as I ran last Friday, for example. 90% is tough to maintain for an hour, let alone three hours.
