Thanks so much for the replies and encouragement, everyone.  Hearing (well, reading) people who know what they are talking about saying that I have any chance at all of someday qualifying for Boston makes me determined to put in the work I need to put in to do it.  Thanks for that !

Redrum, I typically try to run 6 days a week and I spread out the mileage fairly evenly.  My "long run" will usually be 10-11 miles on Saturday with the other 5 days varying between 5 to 8 miles.  I usually take Monday or Tuesday off.  Like I said I don't really plan my speedwork, but as I was looking at my log I saw that I usually will have a speedy day the day after my rest day.  I also like to try to kick it up a notch on Friday before my long run because I like to practice getting used to running longer on tired legs.  When I start training marathon training in June for my 3rd marathon,  I will be working up to a peak of about 60 miles and will distribute the mileage in such a way as to have a longer (between 11 and 14 miles) midweek run along with the Saturday long runs up to 22 miles.

Thanks again, everyone.  Your support is greatly appreciated!

Congratulations!  Also, so glad that you didn't die trying! =)

Way to go! Bet it felt pretty good coming down the stretch seeing that clock starting with a 1!

Congrats! Great job!

I think you have a very good chance of running a BQ if you'll keep running 40-50 mpw and keep doing speed work.  Don't be afraid of occasionally doing some short, fast stuff like strides, "repetition" workouts, and hill sprints.  Sounds like you had a terrific race.  Congrats.

I agree 100% with what Brad said.

I'm so happy for you! Good serious training always pays off. You did so well! And I bet the PRs will be coming fast from now on.  Sub-2 is definitely a milestone!

Congratulations!  Great job!

Congratulations on beating your goal, especially by so much.  Sometimes I think it helps just to be totally focused on a singular goal for a race.  If you need to accept not making it, then you can do that after the race and still feel good too.  I love that you said the heck with that side stitch and just went and got that time.  Keep up the awesome work.
