Ok....anyone have any tips or advice? I'm not sure I am actually going to run one, but I have friends urging me too. I've only done 5Ks so far. But there is a local half here in October. I figure I will start training, and see how it goes. I have some issues with my back, and not sure how distance running will effect it, but I figure I can try. I have never tried this....suggestions?!?!
