This document discusses the importance of recovery periods for runners. It recommends taking 2 weeks off from running to allow the body to rejuvenate from stress and plateaus in performance. During the recovery period, cross-training activities and indulging are encouraged, though weight gain should be temporary. The post-recovery rebuilding phase slowly increases mileage by 10-20% weekly over 3-5 weeks to safely return to full training. Daily recovery activities like stretching, foam rolling, ice baths, proper nutrition, and sleep also aid the body.
