See the prompt

I'm racing a Olympic triathlon and expect to finish in 2 h 40 min. I haven't measured my sweat rate. Conditions look mild, and my gut is in some training for fueling. A race fuel calculator built on the research (Jeukendrup 2014, the ACSM 2016 position stand) gave me: 75 g carbs an hour (glucose and fructose, about 2:1), about 175 g in total; fluid: drink to thirst, no sweat rate yet; 300 to 1,000 mg sodium an hour. Check this against my training and how my gut has handled fueling, then build my race day plan: what to take and when, leg by leg, with real products I can buy.
