I've just begun speed training to increase my running pace. This process is quite arduous! I don't have the physique needed, so it's super challenging. I ran for longer today than yesterday without needing a break, but the pain...it's such a mental battle.
But I can't keep running 5K at my current pace. One, it's not good cardio, because I'm used to it, & two, it's not really running, more like slow jogging or race walking, except I do lift my entire foot off the ground.
Any comments and/or suggestions would be much appreciated.
