i love this old post from antonio cabral:
"The runner that i coach and that did 13:36 with a full time Job occupatioon (7 hours a day – 5 times a week) that´s Rui Lopes. The name may not say noting to you, but the moment that he did that and what did keep my attention and I did try to analyse that´s why with 40-45min continuous runs every day and 1 “weak” workout as Control test once a week (Ex: 4X1000m 2:50-2:52 average 4 min intervals).
Thus that´s very easy to remember his weekly traning schedule
Monday,Tuesday, Thurday and Friday – 40-45min continuous runs going a few times in 3:10 by kilo.
Wednesday – 30min warmup + 4-5X1000m in 2:50-2:52 avarege range with 4min intervals
Saturday and Sunday (if ther´s no weekend competition) – the same 40-45min.
If thare´s a weekend competition – Saturday: 20min easy and Sunday – competition.
I asked to myself – if he is not able to run faster that that in workouts (2:50/kilo that´s 14:10 5000m pace) then why he did 13:36? We were in the early 80s and I didn´t know yet what are LT runs, but it took my attention that the runner did every 45min very fast than their teammates – his continuous runs weren´t easy jogs, but tempo runs.
The history of that run is that he got a good team contract change from my advise to another coach he did start training twice a day and more training volume, more track workouts. Result: Actually he is a 47 years old man, but his PB still remains 13:36 !"
