Running into a "Wall"

I realize I am late in chiming in and I hope you have got the help that you need to get over the wall, but I too was struggling for the past 2 weeks and I knew it was mental, but was really stuck getting through my 8 mile long run.   In talking to a friend she said I needed to visualize myself finishing the 8 miles.  That night after we talked, I tried really hard to visualize myself finishing, but I realized I could not picture 8 miles it seemed like an infinite distance to me.  I have since been online and found something in my normal travels hat was 8 miles.  I am happy to say that I finished my 8.33 mile run yesterday morning and felt great all the way even the hill.
Another friend also recommended coming up with something I am going to say to myself when my breain started telling me I had to wuit or the hill was too long, etc.   IT WORKED! 
From talking to people this is a normal, mental thing! :-)

Now, off to picture my next long run!

Amy,

Thanks for the "pep" talk!!! 

While most of the "wall" was "physical" (my legs gave out), another part is indeed "mental".

I know there are days when I begin and I say "I will do X miles today" and then there are days that once my foot hit the pavement I say "Ugggggghhhhh we're never gonna go X miles".

Tomorrow I am trying for 7 miles. I know I can do it!!!

Then next time I hit that "mental" wall of not breaking the X mile barrier (so far it's 9), I am going to tell myself do 9.01 miles. If I can do that the next time will be 9.02 miles, and then 9.03 miles and so forth. Hopefully doing .0x miles over 9 will get me to my ultimate goal.
