When should cyclists use the SiS GO Energy + Caffeine Gel Box of 30?

The SiS GO Energy + Caffeine Gel Box of 30 gives you a full supply of race-ready caffeine gels: 22g of fast-absorbing carbohydrates and 75mg of caffeine per gel, in the format built for the hardest moments of training and racing. Science in Sport built this gel on the same carbohydrate platform as the GO Isotonic Gel, adding 75mg of caffeine to lower your perception of effort and sharpen focus when fatigue sets in. Note: this gel is not isotonic due to the added caffeine increasing its concentration, so consuming it with water is recommended.

Use one gel 30 minutes before short, intense efforts, or one to two gels towards the end of long endurance events when alertness and power output start to fade. Caffeine has been extensively documented to improve endurance performance by reducing perceived effort and increasing concentration late in a race. Do not exceed four gels per day. Informed Sport certified, every batch tested against the WADA banned substances list. The 30-pack is the right buy for athletes who use caffeine gels strategically across multiple training sessions and races.
