So, I'm running now or something. Walking briskly, with brief bursts of speed. Apparently I'm doing it wrong.
I went with Pedro this morning and he was surprised at how fast I was going, when I was going. I basically speedwalk for about 5 - 8 minutes, then put on a burst and run at (what he calls) "top speed" for 45 seconds to a minute, then continue speedwalking for another 5 or so. I keep the pace up between sprints to keep the cardio going, but apparently it is weird that my only two speeds are "brisk" and "roadrunner." He jogs most of the way, and we both average out to about a 15 minute mile. He says I run three times as fast but only sustain it a quarter as long, and my walking speed is almost as fast as his jogging speed.
I am not having too much trouble with getting overly winded, but my legs are so sore that it's keeping me from sprinting for as long as I would otherwise be able to. The shins, mainly. It's definitely muscle tenderness, not joint pain, so I'm hoping I can just work through it until it goes away. We are both eschewing expensive trainers for flat shoes and using the "barefoot runner" technique of running on the balls of the feet and toes, which actually feels much more natural and comfortable to me than wearing trainers and landing on the heel. But it works different muscle groups than walking does and the shin splints are really keeping me from being able to push myself as hard as I'd like.
Pedro thinks it would be easier on my muscles if I ran more slowly for a longer stretch of time. And he's probably right. But I don't get the concept of running slow. I don't know how to moderate my speed at all. How do I get my body to move as if I'm running if I'm not going full tilt? In my mind, it's binary -- you're either running or you're not. How fast do you run? As fast as you can. If you're not going as fast as possible, you're obviously not running.
What do y'all experienced runners think? Should I keep doing it my way and just keep taking ibuprofin? Am I going to cause lasting damage to my body this way? If I need to change the way I run, how do I turn off this instinct to try to break the sound barrier every time I decide to go full on? Anything y'all can share will almost certainly be helpful.
