Fluid an hour

To thirst

Without a sweat rate the research says drink to thirst. Do the sweat test to get a range.

Sodium an hour

300 to 1,000mg

Nearer the top in the heat. A sweat sodium test gives you your own number.

About 300 g of carbs over the race. That is a 25 g gel every 20 minutes, or the same carbs from drink and chews.

Rehearse it in training first: the gut adapts in 2 to 4 weeks. Costa 2017

See the prompt

I'm racing a Marathon and expect to finish in 4 h. I haven't measured my sweat rate. Conditions look hot, 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 300 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, with real products I can buy.

Questions

São Paulo International Marathon: questions.

  • At a typical finish of 4 h, the research range is 60 to 90 g an hour, as glucose and fructose, set by how trained your gut is. Enter your own finish time above for your number.

  • Temperatures run from about 18 to 26 °C (64 to 79 °F): Average daily low and high in São Paulo in April (Weather Spark). Heat raises your sweat rate, so do a sweat test in similar weather.
