My bad. I don't check the boards like I used to. Aris training plans are a mix of very defined and very undefined. Weekly mileage, as well as things like nutrition, are laid out very thoroughly in the beginning of the season. So if it's cross the team will probably get some sort of hard copy in June of the mileage their supposed to hit each week. Also, they'll sometimes provide nutrition guides, strength training principles, etc through out the year that are kind of ongoing edits that change a little bit each year.
Cross country work outs are often very unorthodox. Rarely is a workout provided to an athlete before practice. Near the end of season workouts are a little bit more traditional, but the three key workouts over the summer and early fall are fartleks, time trials, and the long run.
Most of summer training is steady running. Maybe a couple times a week they'll spruce it up with some fartlek/tempo stuff intermixed in the training run but it's never timed or measured. They're pretty big on time trials. A 5k time trial in the beginning of the season, sometimes a 10k. Usually a 2 mile time trial around the time of Manhattan on the track.
Early season cross country workouts are pretty much based on time only. Aris has an idea of what he wants accomplished and how long it should take, and after that it can get a little screwy. Run this hill, run this loop, now do this, now do that. Until his watch hits a certain time and then almost always some sort of finishing effort that's run close to all out. I think this structure of workout is what makes answering training questions so hard and why he can be vague in interviews.
In the last four years a lot of emphasis in training has been put on adding quality to normal and long runs. S.W.E.P (speed with endurance process) is almost always included in their runs, outside of recovery runs which they do a couple times a week. Sorry if this is written poorly, I'll try to come back on here after work and write more concisely.
