I was studying abroad this Spring semester and thanks to my recovery inhibiting lifestyle ended up with a case of suspected Overtraining Syndrome, starting mid-March. After 2 failed rest attempts (4 days off in April, 15 days off in May) I took a third break for 2 full weeks in June. I have slowly been building up since June 21st (about 6 weeks), running no more than 4 days in a row, and hitting at the most 37.4 miles in one week (in the past I have handled 70 mile weeks without difficulties). I have been getting plenty of sleep, napping most days, and avoiding caffeine and alcohol for pretty much the whole summer. My runs have improved since my return to running in June, but overall still feel pretty terrible.
My question is: is it normal to still be struggling with overtraining syndrome 6 weeks after my break or do I need more significant time off?
