Lots of slow miles, a little bit of tempo running, and an interval workout here and there, all done with a heart monitor. While a training plan is outlined, it’s pretty standard. The problem: I’m still not sure what to do differently to achieve said endurance. Stu did a great job of getting me pumped up to change my diet and training regimen to reach levels of endurance I’ve never dreamed of. For example, Stu contends that “the wall” is simply a construct invented by people trying to sell us sugary sports nutrition products, and if we don’t focus on it, we won’t hit it. There are a few other positives, mostly the form of motivation. (And Stu ran 1,000 miles in less than 12 days, so he should know!) By doing most of our training at a very slow pace (heart rate less than about 75% of max) and consuming almost no sugar, especially not while running, we can train our bodies to burn fat longer and run farther. Fat-burning takes place when we exercise slowly and aerobically sugar-burning happens when we’re exercising hard. Stu’s message: we have a lot more energy available in the form of stored fat than we do in the form of sugar.

The problem is that the “how” can be summed up in just a few sentences, not an entire book. It’s not that Stu’s message isn’t interesting - the idea that we can train our bodies to burn fat rather than sugar in order to run far longer than most of us realize is possible is certainly worth some exploration.

I say “finally” because it became a bit of a chore. Well, I finally finished Stu Mittleman‘s book, Slow Burn.
