I'm bringin running back...ya! wrote:I know you need to periodize, but if I was a little short on time, which type of training should I do the most?
If you're "short on time," the most important work is the most specific work: two or (preferably, if you can handle it) three days a week of work at your goal pace (3:50/1500m = 15.7/100, 31.3/200, 46/300, 61.7/400, 76.3/500, etc.); a bit slower than your goal pace; or just slightly faster than your goal pace.
These probably should be on non-consecutive days, although a low-volume, slightly-faster-than-pace session on Day 1 could probably be followed by a substantial-volume, slightly-slower-than-pace session on Day 2.
Days between pace sessions should be *easy* aerobic sessions: distance running or other aerobic work (cycling, swimming, elliptical, etc.). There *might* be benefit to a longer aerobic session, every 7-10 days, but it should still be at an easy intensity level (and could still be alternate-aerobic work, either in place of or combined with running). Taking the occasional day completely off is also acceptable, and probably wise.
Your pace sessions need not always be on the track. If you can find accurately-measured off-track venues, those are fine. Note that they don't have to be dead flat--a little rolling terrain is fine (vide Seb Coe's road and park sessions).
Please: I know that this is not most people's theoretically ideal training routine. However, it responds to the realities of the OP's actual situation and question. You're never coaching an *event*--you coach individual athletes in their real-life situations.
