Let me ask you a question. Is your in-season running training the same as your pre-season/summer training?
No, of course not...
So should your in-season lifting be the same stuff you're doing in the summer?
Again, of course not.
Lifting, like running training should be periodized. Whether you follow a traditional linear progression or an undulating progress is up to you... (I tend combine the two by setting main goals for the point of the season but also "touching base" with other types of lifts every few weeks).
When I was in college our peak season was mid October- early/mid November (late november if you were good). My suggestion is mimick your lifting off of what you're running. So:
Early summer- getting use to running again, get use to lifting again - low weight high reps (very brief period, light muscular endurance stuff)
--Notice: No hypertrophy phase because it's pointless for runners because you wont put weight/mass on... Nearly impossible running as much as you do without eating like an absolutely gross freak.
Main summer- building base/strength, same for lifting, build strength- 85-951rm for 3-5 reps
Early season- Some harder workouts, maybe incorporating reps/ longer intervals and stuff. Same with lifting, incorporate some plyos. (This part of the season- through most of september- lifting should be highly variable/undulating. This means a mix of heavy weight, some plyos, some maintenance days, maybe some olympics if you're into that stuff (seems to help)
Peak season- occasional plyos,occasional olympics, very ocassional (once every 2 weeks if that heavy stuff (3-5reps) just for maintenance).
Don't lift when you're suppose to be peaking i.e. take a week off if you have a championship race/ at the most some light plyos.
This is based off of anecdotal and scientific evidence. It's worked for myself, teammates, other athletes I've worked with and I have researched and even experimented on this stuff extensively.
Sorry if there are spelling issues I don't feel like re-reading it all.
