You're going to have different amounts during fall and spring training. You tend to run a lot more miles in fall training then your spring training (some coaches run programs where this isn't true, but most of them will do it with more miles in the fall). That being said…here are fall mile approximations in my experience. Oh, and I'm not talking about track workouts. I'm just thinking about days where your objective is to go out and run some miles.
400m or less- 400m will be maybe as many as 10 miles a week. anything less, you shouldn't be running miles.
800m- at least 25 miles a week during the fall.
1500m & mile- probably around 30-35 miles at least.
3,200m- I'd guess around 45 miles
5,000m- many many miles
10,000m or greater- many many more miles.
Once you get up to the 5k range, theres a lot of variability in programs. Some coaches only have you run around 50 miles a week, some log 70 or more. Its hard to call.
