I've been considering a marathon for some time and the one thing holding me back is I'm aware of the mileage I'd need to log and am asking myself can I seriosuly manage the volume. Reading the opening couple of posts has almost convinced me to remain focused on 10k and half marathons (currently running 40-50mpw). Like most runners though, I feel like it is my "calling" to race one, even if I don't do another for a few years later. I'm also stronger over longer distances than I am 5k and 10k races. My p.b for 10k is 37:03, but I have cracked 1:20 in a half.
Stevie has hit the nail on the head, especially with that first paragraph shich I have unfortunately fell vicitim of, and recovering from overtraining takes a LOT longer than recoverig from general fatigue and tiredness.
If you are telling a forum how tired you feel and asking if you should rest, well, you have answered your own question. Rest up, recover and come back stronger. That is the whole point of training and on return from a break, you may be running faster times again.
You have almost answered your own question. Of the programhave you been following, have you been "prescribed" a range of exercises to focus specifically on glute activation? Hip mobility and lack of glute activation is a very common issue among runners. Personally, I don't believe a change of running style will help, but running those long runs at a slower pace might.
