Sub 3 Marathon Goal - 12 Weeks Out

by thomas25 » Wed Jan 29, 2014 6:18 pm

Hi,
I start my 12 weeks of marathon training next week for an April 27 marathon. My background - 36 yo, running for 3 years, no physical activity 15 years prior to that. I didn't start at 5k/10ks, instead I went from couch to HM in 6 months just working on extending the long run in 2011. Ran a few more HMs in 2012 to 1:31 PR. 2013 - 3 marathons last year- 3:08:29 PR in May 2013 on Pfitzinger 18/55. Peaked at 55 mpw for the final two races - bonked/cramped at Lehigh Valley in the late summer (1:33/2:04). Ran a 1:27 HM last October and targeted 3:08 at Philly marathon. Bonk/cramping again (1:34/1:48) splits. I've spent the past 8 weeks addressing endurance and building up my base from 60 to 80 mpw (rotating 1 tempo/1 set of hill repeats every 2 weeks, everything else easy). The bump in mileage has been niggle-free. I just time-trialed a 59 flat 15K this week. Hopefully this suggests some gains in fitness. Since I've never focused on a 5k/10k cycle, my 19 flat 5K predictably doesn't line up to this 15K, so I still have no speed. I do plan to focus on 5k/10k after this marathon cycle.

So, for the final 12 weeks, I'd like to stay at 70-85 mpw with one mid-week workout and rotating the long run every week between a 3 hr 22mi aerobic run, taking no carbs, to work on fat burning and then an 18 or 20 mi long run with MP miles building up from 8 MP miles to 16 MP miles 4 weeks out. For the mid-week workout, next 6 weeks, I'm thinking of addressing my vo2max deficiencies by doing 6x800, 5x1000, stuff like that. Should I also throw in 10K workouts like 6x1mi and 10x1000 or just focus on vo2max for 6 weeks? The next 4 weeks I'm thinking lactate threshold runs at 1 hr race pace. I'm racing an HM 3 weeks out on a 2-day taper. I'll target sub-3 FM if I go sub-1:24 HM. Sub-1:25 HM, who knows, maybe sub3 is still possible. Anything over 1:25 and sub3 is off. And then taper 2 weeks. 10 days out from race was going to try the Yasso 800s +5 min for a final FM predictor but that could be a colossal failure given my lack of shorter distance racing experience.

Thoughts? Thank you in advance.

Post in the Coaching section as not many folks come into the other forums.  This way you will get a lot more responses.

Your 59 flat 15K puts you just under 3 hrs.  It sounds like you have major problems in the second half of the marathon.  Your mileage should should help.  If I was you I wouldn't do any VO2 Max work and would try doing 2 big workouts a week as follows:

Do a midweek MLR (11 to 15 miles) with either tempo miles (build up to 6 or 7 miles) or CV work 6 x 1K + 4 x 200m (don't be tryiing to do 66 x 1 mile or 10 x 1K as this is way too much volume for you) at mile pace with 200m jog recoveries.  You can alternate doing a tempo one week and CV the next week.  Every other weekend I would do some MP work in the long runs.  Building up to 16 miles is too much for you.  I would build up to 10 or 12 miles max and do them after running 8 to 10 miles which will make them pretty tough.  With 12 weeks to go would mean you have about 10 training weeks giving you 5 MP runs if you do them every other week.  Start with 4 or 5 miles and build up to 10 to 12 miles.  You can break them up into intervals when you are building up ( ie 3 x 3 miles with 1/2 to 1 mile recovery, 4-3-2 with 1/2 to 1 mile recovery).  The rest of your runs during the week will be either easy or very easy.

Since you are running a half you can use this as your last MP session.

To me, yassos are not a very good predictor workout.  Doing 20 with 10 to 12 at MP is as it is similar to racing a marathon while doing 800's is not even close.  Different systems are used.  Also,  you don't need a lot of speed to run a good marathon.  Endurance and Stamina is much more important.
