The short version
Pills give you dose control; gels bundle caffeine with carbohydrate you also need. Caffeine has reasonably good evidence behind it as an endurance aid, and the sensible way to use it is deliberately rather than continuously. A gel delivers a modest fixed dose along with fuel, which is convenient and hard to track. A tablet lets you decide exactly how much and when, which is what you want if you are saving caffeine for the night section rather than sipping it all day.
Common questions
How much caffeine is useful?
The endurance literature generally uses moderate doses relative to bodyweight rather than large ones, and more is not better. Very high intakes cause jitters, a raised heart rate, gut distress and poor sleep afterwards. Work out what your own stomach and head tolerate in training.
Is caffeine safe for everyone?
No. If you have a heart rhythm problem, high blood pressure, an anxiety disorder, or are pregnant, or take medication that interacts with stimulants, talk to a doctor before using caffeine as a training aid. Caffeine has also been linked to serious harm in overdose, which is easier to reach with tablets than with coffee.
Does caffeine dehydrate you?
At the doses athletes use, the diuretic effect is modest and habitual users adapt to it. It is not a reason to avoid caffeine in heat, and it is also not a substitute for drinking.

Choose the Honey Stinger Caffeinated Energy Gel if…
You want one thing in your hand doing two jobs. A caffeinated gel arrives with carbohydrate, which is what your legs need anyway, and it is simple to plan into a fuelling schedule. The problem is drift: if every gel in your pocket is caffeinated, you have no control over total intake by hour ten.
