"Take ur easy days easy, and your hard days hard" I completely get why people say don't push the pace on an easy run, it's recovery and all, what I don't get is why people constantly stress that you shouldn't race or give a huge effort for intervals/tempos/fartleks, if you don't put 99%+ in, how are you going to get better? I don't understand the mentality of "not racing" workouts, they're supposed to be hard. Why does it matter if my tempo is 95% effort rather than 90%?
In one workout it might not matter if you overexert yourself, but there is debt you incur and the harder you go the longer it takes to recover. So maybe going 95% in a workout does not impact your next hard workout that one time, but there can be a cumulative effect. The cumulative fatigue can build and build such that you start to compromise later workouts or get into a hole that is much harder to get out of.
A workout should be designed to stress or overload you a bit in order to trigger stimuli for improvement. Going too hard might shoot you past that where recovery (where the adaptations take place) is compromised.
