Fav Gel!
This gel (raspberry) has gotten me through some tough humidity training and a triathlon! The texture is super easy to get down, which is what sets them apart from other gels!

Goes down easy
This has become my favorite gel on a run. Pushing towards an hour you need a bump and this goes down smooth with no water needed.

Easy peasy
I have been using SIS gels for years. They work well, go down easy and the flavors are generally on the mild side.
