Sugar Alcohol Race Gut
Sugar alcohol race gut is urgency and bloating from erythritol, sorbitol, or xylitol in sugar-free race foods—audit labels during gut training, not on race morning.
Sugar alcohol race gut flares when erythritol, sorbitol, or xylitol in sugar-free gum, chews, or some sports foods pull water into the colon during effort. Labels hide polyols under “sugar alcohols” or sweetener codes.
Audit every gel, drink, and pre-race mint during gut training weeks.
Common questions
-
Are sugar-free sports chews always safe pre-race?
No—read sweetener lists. Even small polyol doses can trigger urgency when combined with nerves, heat, and jostling on race day.
