Tapering mileage

Running my second marathon on 27 April, my peak week was just over 50 miles (last week) and now I’m in tapering, the plan calls for 44 miles this week, seems high? Next week it’s a total of 30 miles, the week of the race it’s 36, which includes the marathon.

I was planning to run a couple of 5-7 mile runs and a 12-14 mile run at the weekend this week, one of the runs being intervals.

Thanks!
