Having only run one marathon I wouldn't say I'm experienced, but there are a few issues with your schedule which jump out at me:
- You're running 6 times a week towards the end of your schedule, which I would only expect from runners with several marathons under their belt who are aiming for a fast time. It's too much for somebody who is preparing for their first marathon with only one month of running before starting the schedule. It's likely to get you injured.
- You need a rest day after your long run to allow your body enough time to recover.
- Also, the day before your long run, you are running too far doing 10km. It should be a maximum of 3 to 4 miles (about 5km to 6.5km).
- Your schedule is very repetitive - if you have more variety you might find it easier to stick to in a few weeks' time. Instead of having 2 fartlek sessions a week I suggest you swap them for one interval session and one marathon or half marathon pace session.
- I would also vary the length of the mid week runs rather than consistently running 10km. The mid-week runs should probably range from 4 to 5 miles up to 8 to 10 miles depending on the type of session.
I suggest that you look at the schedules under the training tab on this forum - you will find plenty of RW schedules designed in this way.
I hope that helps and good luck with your training! For what it's worth I used the RW Garmin ready schedules from this website for the VLM this year and am using them again to train for the Munich marathon in October.
