Hi
I was wondering if its possible to run a sub 18 3 mile off more mileage alone. I was running about 40 miles a week with a lot of speedwork, but I always seem to get injured when I do intervals or race pace efforts, so I was wondering If I just built up to 50-60 miles a week could I run it? If so, when will these benefits of high mileage be reaped?
Current PR's are
5:37 for 1600m
12:00 2 mile
20:30 3 mile (maybe could've gone faster but injured all XC season)
