Interestingly enough such a "serious" runner can come from all levels of physical ability. I am no where near being an elite, basically a mid-packer. However, besides my stats, there is no major difference to how I approach the sport vs. more talented individuals. An analogy would be: Is a Class A baseball player necessarily less serious than a Class AA or Class AAA or Major Leaguer?
Ok, so what's the point you may be asking? As a newbie to the forum I perceive a caste system which sometimes sounds, well, elitist (not all participants mind you). Hot shots looking down on us mortals. I think all should be delighted that running is growing in the masses and urge the talented runners and knowledge leaders to always give constructive feedback, even if the forum participant comes from the plebe.
