Update on running/injury

so recently my shins have been killing me and i've pretty much given up on every moderate/easy run. i do well on workouts and stay up for the most part but i just don't have the endurance for a longer type run. plus my achilles and hamstring have been giving me some occasional problems. i don't know if i should gut it out and keep running through it or just take some time off to recover. nothing else worth blogging about besides that we have a workout tomorrow (Motrin ftw) and a possible time trial within the next few days and a scrimmage against ocean on thursday. on one hand i think i have a good shot at breaking 4:40 because i think i can definitely stay up with group one on some of the harder workouts if my shins will let me but on the other hand, falling of on easy days doesn't really boost my confidence and my shins are still shit.
