Viren ran up to 200 mpw in building for his Olympic peaks. No doubt that a lot of that mileage was slower than 7 minute pace at altitude.
Plenty of guys including Rodgers and Shorter (who ran up to 170 miles in his Montreal build up) ran slow through most of their training. The secret for them was building a huge base around their workouts. And to stay healthy it required going slow enough to recover even though they were capable of running much faster.
also, one thing to think about is the percentage of miles at a hard pace. Now, Viren ran 200mpw- if even 20% of that mileage was at a hard pace/race pace/threashold pace - whatever you want to go by - that is 40 miles per week. And if you think about racing 5ks and 10ks, doing 40 miles per week of hard running should be awesome preparation for racing , since the races are about 1/6 of the total hard mileage.
compare this with a runner racing 5 and 10ks and training about 5-10 miles per week of "hard training". The ratio is much closer. SO - I think once you have the quality training up to a decent ratio COMPARED TO racing distance, THEN you can add tons of slow miles and they will help. After all, i think a runner can only run so much hard mileage per week before breaking down - they have to add moderate paced miles. but i also think the best runners have added slower miles while simultaneously running a high enough percentage of harder runs.
