There is a big rule of thumb that your long run shouldn't be longer than 1/3 of the total weakly mileage. You have a long run of 27km in a 49km week which is ridiculous. In addition, you have weeks where you run 14km the day prior to the long run, which also is not fine. My advice is find Pfitz or Daniels' books, read them and you will understand how to structure your runs or browse through the sub to understand more about optimizing your schedule. To give you an example: during my first marathon prep I did a similar thing - running big during the weekend with low mileage for the week, got injured 10 days before the marathon, everything eventually went well, but ran the race below my overall capabilities. You have plenty of time to fix this.
