ENERGY BARS

Energy bars are essential fuelling for long rides. But which of these effectively combines science and taste? James Witts tests eight…

Unlike energy drinks and gels, which are flexible enough to cover all three disciplines of triathlon (well, pre-swim), energy bars are mostly the preserve of the bike. Yes, you can consume before you race and train but it shouldn’t be needed – a good hearty meal should be sufficient. It’s on two wheels that energy bars are key for various reasons.

The first is down to the non-weight-bearing nature of cycling, which means your torso isn’t oscillating all over the place and so your stomach can digest without outside interference. Also, because your saddle, frame and wheels are accommodating your load intensity is generally lower than on the run leg. Again, that takes strain off your stomach and improves digestion. Energy bars also offer a welcome solid break from low-viscosity fluids and moderately viscous gels. While this is recognised by your tastebuds and stomach, it’s not by your intestine, which is where glucose is absorbed into the bloodstream and then to the working muscles. So the usual rules about consuming 60-90g carbs an hour apply. That means some of these bars here require a water chaser rather than further energy drink that could result in gastric distress.

And remember there’s always the complimentary homemade energy bar option, especially over Ironman where flavour fatigue is common.
