Yasso 800s and my WR prediction

The White Rock Marathon is only 11 days away.  This will be my 4th consecutive White Rock.  This morning I ran my last Yasso 800s leading up to White Rock.  Yasso 800s are an interval training workout that also serves as a predictor of marathon finish times.  (See my entry on Yasso 800s from this time last year here.)
This morning I averaged a 3:35 800.  The best thing about it is that if I leave out the first interval (I wasn't quite warmed up yet), intervals 2-10 ranged from 3:31 to 3:36.  I am encouraged by this consistency and by the strength of the latter intervals.  My normal pattern on intervals or tempo runs is to taper off with slower times at the end, and to be inconsistent in pace throughout. 

So based on the Yasso 800s philosophy, this should predict a 3:35 finish at White Rock.  This is actually pretty encouraging; my marathon PR is 3:35, set at White Rock 2009.  There are lots of factors, and Yasso 800 times are no guarantee, but I have been putting in more miles more consistently in the months leading up to WR  than I did last year.  (I'm at 87 consecutive days of running, and counting.)  Maybe, just maybe, I have another 3:35 marathon in me.
