The issue isn't whether or not to push the pace or train hard, but how we should use our training time most effectively.
Apply stress, take it away, get stronger. Repeat.
What type of stress, when, how often?
Let's say you've been training for a marathon for 14 weeks you have 8 weeks left. You need to taper in there so that leaves 4-5 weeks of build. What do you do with that time to get the best out of it? If you're training to run 6:10 pace for 26.2 miles you should probably dial that in so you have an MP workout every week. Threshold is important so lets throw some of that in there. What next? Let's say you'll have 2 weeks of increased volume and intensity and then a rest week and then two more volume and intensity weeks. I say throw throw 2 fast-finish long runs into the last week of volume/intensity on those cycles. But I would say that those would be the only ones in the Marathon prep.
