You don't really have a choice about whether or not your mileage stays up. It is inevitable that it will drop.
For example, my school has two races a week. The day before those races we probably wouldn't do more than 5-7 miles just to get ready for them. Once a week we do speedwork, and you only would do maybe a maximum of 5 miles on a speedwork day if you include your warm up and cool down. Also the day after a meet/day before speedwork could maybe be your longest run of the week, maxing out at 7-8 miles, but our team usually does our tempo runs that day, so it's usually only 5 miles. That brings the weekly mileage over six days to only a maximum of 33 miles, while over the summer we could be doing 50+ miles in six days.
I guess you could still keep your mileage up if you do include a long run once a week of maybe 10-13 or more miles on Sunday, but as AudienceOfOne pointed out, it is also part of peaking that your mileage goes down.
