Well, call me negative-nelly... but I think that some people are runners and others are not.
Now, does that mean that people who are not gifted runners, cannot run? Nope. It just means they have to work twice as hard at it, and will still probably be twice as slow.
From experience... and months of hard work and dedication... I have learned that my body rejects running. Yes, REJECTS RUNNING. It simply hates it.
No matter how long I run, how far I run, how fast or slow I run... I never get better. The more I run, the more my body rejects it.
Recently I have picked up a nice little GI issue. Not pretty, let me tell you... and it's all related to running.
When my body isn't spewing disgusting stuff after a long run... my body hurts. My feet, lower legs, etc. In fact, the pain in my lower legs popped up about 2 years ago and there doesn't seem to be a medical reason for it, or a fix.
OH... but wait... let's not forget the SIDE CRAMP I get from time to time. Lucky me, that typically pops up when I race (triathlons). That's always fun... running hunched over with my fingers jabbed into my side... breathing deep... again... my body REJECTS RUNNING.
With all of that said... I do put in an average of 80 miles a month running. It's slow, it's painful, it's never fun... but I do it. I kind of have to for my triathlons.
So, I may never be a great runner (trust me on this ladies- I won't be)... but I trudge along... getting it done... and I finish the miles. Even if ladies pushing strollers pass me... I finish.
Sorry I couldn't be more positive... but I truly believe that some people are gifted runners, others are not. I couldn't tell you what your fitness level is, or where you fall... but just keep at it... and if you do... you too will be running 12 minute miles!
Seriously though, it did take me a good 2 or 3 months before I could run a mile without walking.
