Some tips here
Take a days break in between runs, but that's already been discussed. Honestly I'd say do the elliptical trainer instead of running. Running a lot will seriously damage your knees over time.
Don't run for an hour, you can do elliptical but I'd say you shouldn't run for an hour.
Do not fucking sprint and especially don't fucking sprint up ladders. Research the proper method of running down to feet and all.
I'd also suggest "altra" running shoes. I can tell they make a difference by walking alone. I haven't been able to run in over 5 months now since an injury
