I get tired of all the sugary GU and energy bars at the end of a really long ride, the Nuts & Seeds mix still tastes good at those times. Just the proper mix for my pallet.
I do endurance cycling and running. My mentor tells me a need to take in about 200 calories per hour on runs and rides over an hour. These Clif bars do a perfect job for me: easy to eat, no indigestion, good energy boost. The Chocalate Brownie version is one star down only because I like the Clif flavors that are frosted with a sugar coating a bit better.
