Just recently saw an article, there's a study where researchers look at all the data on Strava, and concluded that higher weekly mileage correlate to better performance in distance running, even for 5k.
But I strongly advice non elite not to emulate the elite level of mileage, coz their easy runs are in 4min pace, hence achieving those high mileage are in safer duration. For us, we take a longer duration to achieve similar mileage for the same intensity, hence our trimp 'suffer' score is a lot higher, and injury risk is high. For the last two SCSM, I have been using duration based for those easy and LSD runs instead of mileage. No injuries as opposed to when I tried the Pfitzinger's training plan, where I had shin splint in 2022 and prior to COVID.
Do update us here. Hope just muscle sprain/pull and not herniated disc L1-S4
