when should you hit your peak base mileage. Some background info is that i'm going to be a sophomore at a D3 school with a 5000 PR of 15:26. I wanted to get up to 75 mpw and hold that for about 8 to 10 weeks. It looks as though that this first week in august will be the first time I get up to 75 and I feel like I may be a little behind schedule. Am I? When are you suppose to get to your highest mileage?
