On long rides I use gels, every 30 minutes on rides over 3 hours. On races under 3 hours I use it as well to keep my legs turning over well. On the longer rides I carry a flask or two of gel instead of single packages. The single packages are wasteful and can get expensive.
For the past 4 years I’ve used Hammer Gel’s hard plastic flask. I’m excited to see how the new(ish) Soft Flask from Hydrapak works out. I’ll be able to roll up the bottom to get the last drops of gel and it packs up smaller after use instead of taking up a ton of room in my pocket or bag.
Do you use gel? How do you carry it?
