Changing to a five day split

I need to change my training routine again. Can't seem to stick to one due to changes in my week. Last week I implemented my marathon into my weight lifting programme. I found that I spent a long time in the gym, almost 2 hours for two body parts and about an hour  of cardio, which includes my marathon training.
This was eating away at my day and I wasn't going to the gym at 7am and not sleeping as well as I used to.
I had no problem recovering from my weight lifting but recovery from the long run that I did on Sunday is slow, still sore today even with a high protein intake plus the L-Glutamine.

New routine will be a 5 day split working one body part per day and implementing cardio.
Monday: Chest + Light cardio
Tuesday: Back + 30 min training run
Wednesday: Arms + Light cardio
Thursday: Legs + 30 minute training run
Friday: Shoulders + Easy walking
Saturday: REST
Sunday: Long training run

I will use this programme this week and see how it goes. I am hoping that I see good muscle gains, recover faster, hopefully manage to have more time in my day and sleep better.

Overtraining? Time to reassess

I feel rough today. Bad night sleep. Pulled my neck muscle again yesterday whilst working on back and shoulders. Shoulders is one of my weakness' so I hit them twice, once on Tuesday and than again on Thursday. The BCAA's and L-Glutamine that I am currently supplementing seem to help muscle recovery but not preventing injury from muscular imbalances.

At the moment I am enjoying my pre-workout protein shake before I go to the gym to hit legs. Leg is sore so I might have to avoid dead-lifts and squats, but I shall see. I will however try to go for a run, still need to be training for my marathon and still need to work on knee rehabilitation.

Anyhow, here's my protein recipe for today (similar to others):
400ml water
2 scoop PhD Pharma Whey (Cookie dough)
5g L-Glutamine
Half banana
1 egg white
1 teaspoon organic honey
2 teaspoon organic almond butter
Pinch of cinnamon and nutmeg

3g BCAA capsules upon awakening

For next week I am going to change my workout routine to this:
Monday - Chest and triceps
Tuesday - Legs
Wednesday - REST
Thursday - Back and biceps
Friday - Shoulders
Saturday - Badminton
Sunday - Marathon Run Training

I will have to include two runs during the week for marathon training but currently don't have the time and my knee has not improved enough for me to be able to run pain free.
