It sounds as though you're having him stand to pee? He may not be ready for that yet. But, at this point, he may oppose sitting to pee. My son was able to master it all by sitting on the pot, the trick for him was to sit on the pot facing *backwards*. By sitting backwards they are more secure and don't need to hang on which frees up their hands for directing flow and for wiping too.
Standing, a little guy almost definitely needs a good solid step stool. Positioning it and him to the side of the toilet instead of the front makes it easier and also gives him the tank of the toilet to hold onto if he feels insecure. Another little trick is Cheerios. Cheerios have for a long time been a great aiming aid for little guys. Throw 3-5, or more, Cheerios in the water and have him try to hit them with his stream. Use more at the beginning to give him greater opportunity for success.
Oh, as far as the mad dash to the bathroom, I don't think I've ever known a little boy that didn't get so involved in playing that a mad dash was either necessary or already too late.
Last, but definitely not least, realize he's doing really well already. Little boys usually train later. Right now though, it really sounds like *you* are the one potty trained. Maybe you need to take a couple steps backwards, ask him once in a while if he has to go, but wait for HIM to be ready. It sounds like he may have the physical control, but mentally, maturity-wise, he just doesn't sound ready.
If he really does have to go every 60 minutes, you may want to talk it over with his pediatrician. A dozen or so wet diapers is what you expect from a newborn, not a 2-year-old. You may want to discuss the training issue with him/her too. Good luck and relax, ask yourself the question... "How important is it?" That question has saved my sanity on many occassions.
