Sad? I don't think I said anything sad or anything but positive and supportive stuff. Hell, I have run hundreds of thousands of joyful miles and have performed pretty dang well up to my late fifties.
And I think you are also off on the "talent" idea. It IS true that well-planned, intelligent training and health practices combined with lots of hard work and miles (done with reasonable limits) can pay off with some pretty good results for the non-gifted runner. Undeniable--well, you can deny it, but you'd be wrong--or at least wrong-headed.
My times were not any better than second-rank in most distance races, and I have only one one open division race, out in Chicken Head Arizona in August.Talented persons who put in my hundred mile weeks and track workouts and regular racing and, well, yes, tough-mindedness, were running sub-2:30 marathons, 4:30 miles, and 1:50's 20-milers AT forty-five yrs. (Look up Jack Foster some time.) After months of training for a 10k in Chico, CA, with a bunch of Bay Area seniors, on the track, in the hills, and on the roads, on a good day and feeling great, I could only manage a 34:46. Several guys from our training group beat my butt by a minute or more, and they were several years older.
Oh, yeah, smart hard work and savvy make up for a good bit of talent.
Cheer up, man, you just have to put in the work and keep a positive attitude. Oh, and miles.:)
