Congratulations on your many successes.  I am so happy to hear about your longer workouts because this is what I have maintained for years that the distance has to be achieved and even over-compensated in training to prepare for the endurance of competition.  Honestly, you are probably your own best coach and can probably develop a routine better than the experts for your individual strenghts and goals.  The same advice does not work for everyone, as you know by now, but looking at different opinions and experimenting with various training options might be helpful.  For example, take a look at  http://www.sub3hour.com/

Thank you for sharing and best of luck!

I disagree with the more than your race plan but that is what makes it such a great race, look up the Hanson's training plans they are training Desi for the trails!  They have several good plans, I use a coach who writes my plans for all my Fulls and Half's.  I thing for sure is you learn from each cycle and race, Good Luck.
