I guess I will give you my two cents since I have a good buddy whom I keep writing about that is a pro racer and has gone to the Olympic trials for Marathon. I consider myself lucky to have his advice so I will be happy to share what he has given to me with you.
First, can you be in good enough shape to do well in the marathon in the time allowed? No. Can you prep yourself to finish if that is what your goal is? Probably. I will give you the
workout given to me for a half marathon. What you will need to do is increase your distance and make sure your body is recovering fine before you up them agian. Since you are already running 30 miles/week you are at the "magical" minimum mileage that is a good base and will allow you to do some longer runs.
Here is the half marathon
workout that I talked about before that would be great for the OL-H because it makes 6 easy and 15 no stranger.
*Note* You should be at the 30 Mile/Week level before starting this.
Monday: 5-7 Miles
Tuesday: Intervals (Speed)
Wednesday: 5-7 Miles
Thursday: Tempo Run
Friday: REST
Saturday: 3-5 (Easy) Jog/Stretch/Relax
Sunday: 10-15 Miles (Long Run, Consistant Pace, Good Form!)
Intervals: 1/2 Mile Repeats 880x10 w/ 440 Jog Recovery
Tempo: 30-60 Minutes in the above
workout at 80% Race to Full Race Pace. This should be 5-10 Miles.
Once your body is comfortable in this routine you can keep adding distance for the Marathon. For the OL-H guys there is really no need to add distance.
Other pointers:
- Run where there are hills
- Run on trails when possible
- Ensure your body adjusts to each distance increase
before adding more distance
