If you have an old extra helmet, pair of shoes and a couple of water bottles, keep them in the trunk of your car in case you forget your favorite helmet, shoes or bottles when you drive to a ride start.
They don’t weigh much or take up much space, and they can be a ride-saver should a moment of forgetfulness strike you! Or if you’re at an event or group ride, someone else might have forgotten something that you can lend them.
Remember: Anything that Can go Wrong WILL go Wrong. Use Murphy’s Law to your advantage!
