You probably don’t need them for regular riding/training. They offer little over cereal/cake bars from the supermarket in my experience. I personally like nutri grain elevensies since they are soft and easy to eat.
However, I find them useful in longer or harder races. In long races (4+ hours) my ability to eat solid food reduces over the race. I will start on real food and gradually work my way through to energy bars then to gels for the final push. In harder shorter races this point comes quicker.
Anyway some are good/nice although I find them pricey (which is the main reason I don’t buy them).
My preference is for the zipvit ones as they are soft and easy to eat. 20% off this weekend with ZVENERGY.
Failing that
discount suppliments
energy 4 sport
are my usual first point of call followed by seeing who has offers on. Ribble do at the minute if you want short dated stuff.
