I have long been obsessed with ultra runners, having first read Born To Run and Natural Born Hero’s by Christopher McDougall, as well as Scott Jurek’s Eat and Run. I listened to a number of inspiring Ultramarathon podcasts, so riveting that I still remember where I was for some of the inspiring and sometimes crazy interview.
Recently I have fallen into some other resources thanks to YouTube’s algorithms that have kicked me back into training videos on running, like the Running Channel and an Australian group of trainers for runners over the age of 50.
The biggest change in philosophy that I have adapted is that running needs additional strengthening to stay uninjured. What I used to do was just run, with a few sparse activities as “cross-training”. Being younger, I mostly got away with it, but I did stop running a couple of times from a self-diagnosed meniscal tear in my right knee. I stopped for a prolonged period of time after the marathon in part because I wasn’t prepared for the down side of the marathon.
What I learned watching those videos is the concept of zone 2-3 training. The concept is basically that when you push your body to its limits, you can avoid injury if you spent a large part of your training in a low impact zone instead of pushing your limits constantly. Here is a nice summary of the concept:
The basic proportion is 2/3 1/3, with the goal of building endurance by staying in the cardiac aerobic zone of 60-75% of maximum heart beat for 60-75% of the activity.
