I was on my own through my freshman year of college, but managed to walk on the team for this coming year. Ran 24:43 for 8k in mid-October on a decently fast course and then reduced mileage so I wouldn't put future testosterone/performance levels in jeopardy.
I typically ran about 50 mpw during high school, and decided to bump it up quite a bit last summer. From mid July through late September, I ran about 75 miles a week for 3 weeks at a time, and then would drop down to about 60 for one week to recover (basically I'd remove doubles). This is clearly a big jump, and probably wouldn't have been sustainable if I had continued to do it throughout the spring. Now that I'm more developed, it will start to make sense for me to keep this mileage (or higher) throughout the year.
A typical week looked something like:
Monday -
am: 50 minutes easy
pm: 30 minutes easy
Tuesday (always some kind of intervals) -
am: 15 minute warm up, 5-5-4-3-2-1 (minutes) fartlek, where recovery is equal to the length of the next rep, 15 minute cool down
OR same warm up and cool down, 10x800 in about 2:24 with minute jog rest on bike path
OR
hill repeats
pm: 4 miles easy
Wednesday -
am: 75 minutes easy (about 6:30 pace)
pm: rest
Thursday -
am: 50 minutes easy
pm: rest
Friday (always a tempo) -
am: 15 minute warm up, 25 tempo followed by 4x400, 15 minute cool down
pm: 30 minutes easy
Saturday -
am: 50 minutes easy
pm: rest
Sunday -
am: 14 miles at around 6 minute pace or 100 minutes easy (did the faster long runs later on in the season)
pm: rest
This seemed to work well at giving me a pretty huge improvement from high school performances.
Mileage for track season was usually 55-60 with lots of quality track work (pretty much the opposite of the outline above). Ended up with 3:51 for 1500 which was a little disappointing given some of the speed workouts I did. I think I will do much better in the future off of a higher mileage approach given my physiology.
