toke 2 months and have gotten back into running, my zone 2 pace used to be \~8:15/km, and is now 7:30/km. meanwhile my tempo pace has slowed by 1 minute a km. why? im assuming this is because previously i was overtraining, but how do i avoid overtraining while keeping up mileage? i was only running 4 times a week 25-30 km.
