Intended to do a slow 5k, but went out quick. Slowed pace down a bit, but wasn't feeling too bad by 2k, so decided to keep up pace around 5:00/km. Moderate stitches on right side around 3k mark onward, but fought through them and finished nicely under 25:00. Breathing was heavy-ish over last 2k with increased effort. No knee pains to speak of.
