Gels, chews and electrolytes to test on your long runs now, so your stomach already knows them on race day.






Balms, a waterproof roll-on and blister tape for the thighs, underarms, chest and feet that always rub after mile 6.





A no-pin bib belt, a pocket for keys and gels, a GPS watch to pace with, sunglasses, and cheap layers you can toss at the start.







Blister-fighting socks and no-tie laces, so your feet are the last thing on your mind at mile 20.





Protein, a changing towel and a place to hang the medal, for the hour after you cross the line.
