A slightly noisey podcast due to nearby building work.
My favourite this month was a superb Australian article proving how poor labeling is in supplements - the industry must do better than this. A review through some interesting options for pre race optimisation such as coffee mouth rinsing, defecation, topical bicarbonate, some interesting new ideas to explore.
