Here's some math for the OT Hopeful to consider...
672 days (1 year, 10 months) until the Trials in L.A. 02/13/2016, but you've got to get your sub 1:15 qualifier at least 30 days before.
Come to L.A. next March (03/15/2015) and check out the course (schmooze with the R.D. and meet some of the American Elite) because you will run it either on Saturday 02/13/2016 or as a back-up plan you can sign up for the L.A. Marathon Sunday 02/14/2016. Two marathons in two day. You get to watch one and run the other. You decide which one you are willing to work for. It will be fun, like 2008 when we had the Trials on Sunday and the regular marathon on Monday.
Speaking of work, it doesn't sound like you are quitting or cutting back anytime soon so that decided it for you.
Go for the 1:14:59 half, not the 2:42:59 full.
You don't have time for a full because it requires such concepts as a 21-day traditional taper before and 42 days of recovery post-marathon before you race again. Find a coach old enough and wise enough to explain those to you. It will be easier and there will be more time later (in 2018 and 2019) to run a full marathon qualifier to get into the 2020 OT.
You're wasting your time racing 5 km's and 10 km's.
Train for long distance by running long distance. LSD.
If you were to race 6:13 minute miles over 26.22 you would only be able to do one this year, 2, max 3 in 2015.
Train for the half and you can do 2 this year and 6 in 2015.
You can do a Half as late as January 10th 2016 and have
plenty of time to rest and recharge for 02/13/2016.
5:43 minute miles over 13.11 is more in reach and bouncing back from a bad half is way easier and quicker.
Set your sights on a goal half for 2014, yes, you can do either a test 10 km or 10 miler in the 5 to 6 weeks before that goal race. Same with 2015.
Marathon success requires way more spartan training and also depends on course, conditions and competition on race day
(all factors out of your control).
Say you do a half in Aug/Sep 2014 in 1:28, another in Dec in 1:25, Feb in 1:23, May in 1:21...
see what I am getting at?
6:00 minute miles =1:18:39 How soon you get there depends on you. Then the next stop is 5:55 pace, 5:50 pace and finally 5:43 per mile.
The half will beat up your body less and give you more race experience. The way the others were talking on here they seemed to be saying, "sure, just race 5 km's and 10 km's in place of actual training miles and do lots of speed workouts on the track." Not the way to train for a serious half or full marathon.
As for me, I haven't kept a formal count over the years, but since I have been coaching women since the 1970's and have had an athlete in every U.S. Oly Marathon Trials since 1984 I would estimate that the number I have helped would be 30+ American Women Marathoners who have qualified for the OT. Already I have some new post-collegiates who were too young to run Houston in January 2012, so I guess I can add them to the list which will probably put me over 40. Yes, I am only counting the women once, even though some have run 3 or more OT's.
