Science in Sport do two sizes of their Go Energy Bars – 65g and 40g.  The smaller bars are ideal as a quick snack before running, or during a run.  They’re a little slower acting than a gel, but they do seem to work.

My favourite flavour is “Banana Fudge”, although “Chocolate Fudge” is also pretty tasting.

Other flavours in 40g include Blueberry, Apple & Blackcurrant, Red Berry; and, in 65g you can choose from Chocolate & Orange, Chewy Banana, and Apple & Blackcurrant.

I’m not keen on the more “fruity” flavoured offerings, but that’s just because I don’t much like fruit anyway.

They’re available as single bars, or boxes of 30 (for the 40g) and 24 (for the 65g).
