good to keep a mix to reduce stress on joints etc, so looks like a sensible plan.
wrong thread I know but I remember reading something about people shutting down and collapsing towards the end of an ironman, not because of a lack of aerobic fitness or nutrition but because their nervous system has just been so stressed all day by low grade damage that it forces the body to stop, there's an amazing video of a guy in Kona collapsed on the road and eventually waking up and just carrying on (after a bit of a wobble) that this article pointed to as evidence of the phenomenon. no idea if its just tri science or actual fact..
