GU Energy Labs will be the official energy gel sponsor of the 2019 North American Ironman and Ironman 70.3 events, supporting each with its line of Roctane Gels that are designed for long-duration and high-intensity activities that push athletes to their limits.

Roctane Energy gels provide a boosted supply of essential nutrients in a form that’s portable and easy to digest. These gels are packed with up to three times as much sodium to aid in hydration and three times as many amino acids to help prevent muscle breakdown, as regular energy gels.

They also include beta-alanine and taurine to buffer acidity levels and improve heart function.
