Stash extra nutrition on the bike
Luke Bell straps a Powerbar to his basebar with simple electrical tape. It sits flush against the deep portion of the bar’s airfoil shape. Rachel McBride tapes gel packs to her aerobar extensions that she can tear off the bar while riding. Ironman Melbourne champ Caroline Steffen sets a small jug of Assos chamois cream on her saddle for a race with an extraordinarily long bike leg. She also keeps pills, presumably electrolytes, taped to her top tube behind her stem. Her gels are stashed in a topless water bottle secured in her rear hydration system, which can be grabbed while ridding without removing the bottle.
Do it yourself: Mashing a Powerbar onto the toptube was commonplace about twenty years ago, but there are other, more hygienic ways to bring extra food. Try taping your extras to parts of the frame or aerobars that are both accessible while riding and hidden from the wind by another part of the bike. If you have an extra water bottle cage on your bike, try leaving nutrition in the bottle without a top. And, no littering.
