First, a Michael Pollan-inspired minimalist manifesto:
- Drink some carbs.
- Not too much.
- Some carbs are better than others.
One of the most daunting and mysterious aspects of preparing for a marathon swim is planning a nutrition strategy. And for good reason: Nutrition can make or break a marathon swim.
So, aspiring marathon swimmers often seek advice from their more experienced brethren. But how to sort through conflicting information and opinions?
Following up my previous post on channel swimmer/physician Peter Attia’s webinar about “Nutrition for Open Water Swimming”…
As you may have heard, the topic of the webinar (and subsequent video interviews with Open Water Source) was broader than the title indicates. In marathon swimming, “nutrition” typically refers to the stuff consumed during a swim to provide energy. But Dr. Attia was more interested in what people eat when they’re not swimming – i.e., diet.
