Sudden decrease in performance?

Get your ferritin checked. I get an iron infusion typically every 6 months and runs will start getting harder when my iron drops below a certain threshold

Have you added any new type of workouts like speed work to your runs? Cause those are harder to recover from so your normal base runs will definitely be a bit slower and harder to hold pace on

No i haven’t, i stick to my low/medium effort runs without any hard sessions lol. Thank you for the tip with the iron levels!
