Feel fine and normal, go the pool, get asthma attack after 2 k and have to stop.
Come home to find email request for asthma advice from another swimmer.
Write long email with said advice, based on personal experience.
Go back to pool same day for another try, get another asthma attack, and come home again, feeling crap and like a complete liar after said email.
Feel crap next day, and go to pool for very low impact swim. Get in water and start getting faster as swim progresses.
Bloody asthma. Oh, and on three wednesday’s running.
