Plateau

First I would like to congratulate the Vandy baseball team for getting into the championship game at the SEC tournament.  I'm a little upset because it's a double elimination tournament and we only lost in the championship game to LSU, who we beat the in the first round.   Shouldn't we play another game?  I think this should be changed...I guess I'll do it when I'm commissioner of the SEC.

So, this is about my latest plateau.  I just posted this in a thread at Runningahead...

I think I've hit a running plateau as of late.  I feel more fatigued, I can't keep my +30-60 second marathon pace for as long as I could in the past, I'm not having as much fun, and I find it a struggle to get out and run.

There are a few things that may have played a part in this plateauing...

1.  I recently moved from 500 feet in elevation to 4,200.  Not only do I have this altitude change, but the wind blows CONSTANTLY and the first mile out of my house has a 300 ft. elevation increase.
2. I gave blood three weeks ago before the move.
3. I lost my training partner and have been running alone the past three weeks.
4. My headphone wires keep getting caught in the wind and my camelbak, resulting in me having to adjust my headphones constantly.  I may have to quit running with music.
5. I went from a pretty sedentary job (grad research) to a vigorous job (ranching, thus lots of physical labor, and the hours are long).
6. I've started to lift weights.
7. I run/lift after work.

Does anyone have any suggestions about how to bust through this?   You can take a look at my log.  I have a marathon on August 1st and am trying to get in a lot of 50-70 mile weeks the next few weeks.

Thanks!!
