An Evening with Precision Fuel & Hydration

Wednesday, 11 November 2026 19:00 South Downs Social, Winchester 2 hr

Winchester Running Club invites you to the second of this year's autumn and winter training talks, with Precision Fuel & Hydration.

About Precision Fuel & Hydration

Precision is based in the New Forest. The talk will be given by their sports scientists, who are endurance athletes themselves. The company was founded in 2011 by Andy Blow, a sport scientist and former elite triathlete, after cramp and low blood sodium kept spoiling his races in the heat.

They are the official hydration partner of IRONMAN and the Honolulu Marathon, and have worked with Premier League football clubs, international rugby teams and Formula 1. Olympian Eilish McColgan uses their sweat test. Members who have heard them speak before rate their talks highly.

Why come

If you're running a spring marathon, now is the time to sort out your fuelling, so you can practise it on long runs through the winter. Hitting the wall, cramp and stomach trouble are often fuelling problems. People also lose very different amounts of sodium in their sweat, so general advice doesn't suit everyone. The talk also covers shorter races, including the half marathons and 10Ks in the club calendar.

What the talk covers

  • Carbohydrate, fluid and sodium recommendations for half and full marathons
  • Fuelling for shorter distances

Optional sweat test

You can also have a sweat test on the night.

  • It measures your sweat sodium concentration: the milligrams of sodium you lose per litre of sweat. The result is used to build a hydration plan for you.
  • The test is done at rest, so you don't need to exercise. It takes about 30 minutes. Watch this short video to see how it works.
  • Sweat sodium is mostly genetic and stays stable, so you only need one test.
  • Your sweat rate decides how much you need to drink. We will discuss it at the test and in the talk, but we recommend you also collect some sweat rate data of your own.

A sweat test normally costs £120. It is £99 if you pre-book. At least five people need to book for the tests to go ahead.

Book a sweat test with Precision Fuel & Hydration. This is separate from your ticket for the talk.
