Notes
Started out as an easy run and as the heat and humidity built up, I gradually increased pace to get it over with. Not very pleasant. Splits:
9:18, 131bpm
9:27, 140bpm
9:18, 148bpm (hill to key bridge)
9:04, 145bpm (back down to river)
8:59, 155bpm
8:36, 160bpm
8:02, 167bpm (last bit overpass)
