I start eating after hour 1 and try to ingest something every 15-20 minutes after the first hour.
At hour 1 I will usually have something more substantial like a pb&j sandwich or bar.
I then get into Powerbar gummies and will eat a couple every 20 minutes or so.
At hour 2 I will have a gel and repeat this pattern for the full ride.
I also aim to drink at least one bottle per hour but often drink more than that depending on water stops as I do not stop to eat on a ride only to get water or take a leak.

Outside of gels/gummies I also eat fig newtons, almonds or other nuts, trail mix and any other easy to eat food.
