Our athletes talk about it.
"For ultras, the tolerance is incredible: I concentrate the energy in a flask and I can go for hours without my stomach ever giving out."
"My profile is very salty. The sodium fixed on my perspiration resolved my cramps on long climbs."
"The encrypted protocol takes the mental load off me during a race: what to take, when. I can focus on the terrain."
"My fat-burning capacity is high: adjusted intake, no more bonking in the second half of an ultra."
Your protocol, calculated for your effort.
