hi guys.. was wondering how do you use the timing chip for PNM ? its a round button instead of the normal d-tag attached to your running bib used in other event.. sorry for the noob question

hei guys... anyone have any experience with timex gps watch ? wanted to get one but heard rumours that timex gps watches have some durability issue. Was also considering garmin 10.. cheap and simple.. but oni got 5 hrs battery life ..... would barely make it for a marathon... any advice ?

hi sifus out there.. for the coming marathon i will like to bring my iphone, my mp3 player (similar size to ipod nano), my 2 credit cards, cash, car keys and 4-5 gels.... should i get dual-spibelt or single spibelt with gel loops ?? any suggestion ?
