crash stretching!!!

Some people manage to lose weight dramatically - crash dieting, I'm hoping some crash stretching will get me back on the road to performing the way I should be! The last few races have been very frustrating for me, Eagleman and last weekend at Rhode Island. Both races on the bike, I quickly found my left leg feeling numb from my gluts down and my right side with a 'nervey' pain originating in my lower back, running through my glut and the outside of my leg. Along with this a significant lack of power! Realising I am just soooo tight in my hips, through too long of not enough stretching and taking care of myself the way I know I should have, its all added up. I've spent the last few weeks with a much higher focus on stretching and recovery, but now its a case of recovery and recuperation first and some training in between to simply 'keep my oar in'. Not the most ideal way to lead in to my first Ironman of the year, but I'm seriously hoping I can turn things round and get to Lake Placid in the best shape I know fitness wise, I am in...
