89% humidity.
Official: 20:12.73
GPS: 20:11.3
Ran without looking at watch, tried to max out as much as I could.
2nd or 3rd fastest 5k, although still almost 20 short of PR last month.
Legs still have power but breathing was difficult the whole way.
The first mile went out too fast and took a while to adjust my pace. Legs felt weak in the first mile and got better and smoother later, but breathing couldn't keep up.
