  Hey fellow runner, If you’ve been following elite running at all the past year or two, you know there’s a controversy over a “new” product called bicarb. Along with super shoes, bicarb has been attributed to the recent assault on world records. But, does it really work? Or is this just another “overhyped” product beetroot juice was a few years ago? Well, that’s what we’re going to explore in this article. We’ll look at the research and… Breakdown what exactly bicarb is and what it’s theorized to do Look at the early research and why it’s only now becoming popular Dig deep on the more recent scientific literature to see if it has any merit And finally provide some practical strategies should you want to try it.

  These Are the World’s Fastest Marathoners Here’s a complete list of the world record-holders and all-time top 26.2-mile runners. by  Scott Douglas Updated: Sep 21, 2025 6:44 AM EDT Saved!

Alex Hutchinson Zone 2 Training

I hope you’ll head over and give it a read (using  this gift link  if you’d like).   To write it, I spoke to many more scientists beyond those quoted, and had a chance to dig into some of the nuances of the topic in a way that I couldn’t fit into the article. So I’d like to use this newsletter as a place to “empty my notebook” and share a few additional thoughts about zone 2. This gets a little detailed and technical, so start with the  NYT  article and proceed with caution!   Why are mitochondria so important for health?   In the article, I mention Iñigo San Millan’s belief that mitochondria are an early warning sign...
