small pouch for my cell phone while running NYC marathon

Sounds like you need a race belt that has a small pouch. Skip the cell phone you can always borrow someones. Tie your car key into your shoe lace. Why do you need your driver's license? Just curious? Put your asperin in your running pocket in your shorts?..Won't they have gels along the route?

Not sure where you could get it on the spot but this is a website that carries what Im talking about.

Hydration belts come with accessory pouches of various sizes and shapes to handle this sort of thing.  Decent running shops in NYC will carry them.

But I have to ask: why do you want to run with a cell phone? I've occasionally carried one on late night long runs, but at the NYCM there are likely to be a few other people around if you need any kind of help.

Amphipod is a good brand.   I have their fuel belt w/ pouch. 

I also bought a Nathan race belt with a pouch at a marathon expo. The fabric is very soft and non-chafing.  Are you going to the expo???

If you will have the race belt against your skin (probably not this time of year), put body glide on it.

Like people said, you probably don't need your license and cell phone but I would bring gels...I have had races run out of them.  I don't like running a race w/ a belt and pouch but did once.  

 Best wishes on the marathon!

LOL!!!  I guess that you aren't trying to win!  That's awesome!

spibelts are the best!  They are made of spandex, so they're not bulky, but expand to hold up to (I think ) 8 gels.

Try www.spibelts.com or maybe it's not plural (spibelt).  "spi" stands for "small Personal items".

AF

Thats right, I forgot that I actually saw the winner of the 2008 Boston Marathon texting while heading up heartbreak hill!
