A 3:48/km average for the half marathon is a serious, advanced effort — quick enough that breathing is deep and rhythmic from the early kilometres and conversation is out of the question. The pace sits close to threshold, so the race rewards runners who have trained their body to clear lactate efficiently and who have the discipline to hold back through a fast first 10 km.
