Having a bag with all your bike stuff is a great idea especially if you are racing or doing rides. I always recommend to new racers or riders of centuries to start using a bike bag (I use a duffle bag instead of something that was made for that purpose) and a list of things you always need when you ride.

That way, you don't end up at the ride without a helmet, your shoe inserts, your shoes, etc.

So, I've been riding 20 years and only forgot my shoes once and that was for a ride just 10 miles from my house so I went back to get them (i'm usually early for rides) and that was because I just threw everything in the trunk and didn't really think about what I was bringing.

A bike bag makes all the difference. I don't use a list anymore cause I've been riding so many years I know what I need. But, maybe I will start using one again - I am getting older and uh more forgetful
