Hot and humid. Lots of people around me, some within inches on bench. Had build up of broncochonstriction in the last about the last 8 minutes. Air felt heavy. At 4 minutes to go I had to stop because I was breathing very shallow and very quick, lungs were tight. Carried on after inhaler x5. Wheezing sound deepened after I finished. Everyone ignored me. 21spm. 130drag. Felt good otherwise. Hands higher, box-squatting for posture, shins, and leg timing. About 80kg.
