Have a race, event, Ironman triathlon or anything else coming up? I’d reconsider blue cheese and other “moldy” foods in your build-up – here’s a few: sour cream, buttermilk and sour milk; cured, pickled and smoked meats and fish; prepackaged meats, like lunch meats, salami, smoked fish and some sardines; pickles, olives, capers, salad dressing or ketchup; vinegar and soy sauce. I’m not saying always completely ‘em – but nuke ‘em in final few important weeks of performance – and that would include moldy hotel room coffee too.
