I'm hoping for some advice about fasting and marathon training. I started 5:2 a year ago and love it. I started running about 6m before I started fasting and in the past year I have run 4 half marathons with no problem.
I am running London Marathon and in the past few weeks since my long run distances increased beyond 14 m I have found I am a lot more tired with major energy dips. I am also finding myself binging a bit on feast days. On fast days I occasionally feel a bit woozy and out of it. This hasn't happened since I first started a year ago. I do run on fast days but up to a max of 5 easy miles (I've always done this). I also don't fast the day before my long run. I'm currently running 30-40m per week.
I guess I want advice on whether to give up 5:2 until after the marathon. I think it might help me train better and feel less tired in general.
If it helps I have a BMI of 22 and haven't lost any weight with 5:2 but have loved the ease with which I have maintained my weight. I had hoped to continue IF forever and feel scared at the thought of giving it up. Please help!
