Humanity Direct Tring Ultra Hydration Briefing
If you’re going to perform at your best during The Humanity Direct Tring Ultra, you’re going to have to get your hydration strategy right for the 31 miles of epic running. That’s why we’ve partnered with Precision Hydration to give you expert advice and some free electrolyte supplements. Here’s their advice for how to nail your hydration strategy out on the trails...
- Don'tjust drink lots of plain water in the build-up to your run! You can end up diluting your blood sodium levels, increasing the risk of a race-ruining condition called hyponatremia
- Maintaining your blood sodium levels is crucial to performing at your best during an ultra. As well as maintaining fluid balance, sodium plays an important role in the absorption of nutrients in the gut, maintaining cognitive function, nerve impulse transmission and muscle contraction. Sodium depletion can also cause muscle cramps and avoiding it could help you have a cramp-free race.
- You'll be issued with a free tube of PH 1500electrolyte tablets at registration. Just mix one tablet with ~500ml of water and drink it ~90 mins before the start of the race to boost your blood plasma volume and help you start well hydrated (aim to finish the drink around 45 minutes before you set off to give your body time to pee out any excess fluid). The PH 1500 tablets contain ~3x more sodium than typical salt tablets, which makes them ideal for preloading before an ultra. Learn more
- Drink water and electrolyte drinks to thirst during each stage. As a guide, most runners will find they want to drink around 500-750ml per hour, perhaps half of which might contain electrolytes. Of course, the exact amount depends on the conditions, your own sweat rate and past experiences
- Everyone loses a different amount of sodium in their sweat - it’s largely genetically determined - so if you’re a heavy/salty sweater, you may find you need a stronger electrolyte supplement.

- Feeling thirsty? Have a dry mouth? You may not be drinking enough. Try to respond to the early signs of thirst and not leave it too late
- Bloated? Fluid sloshing around in your stomach? Need to pee often during the stage? You might be drinking too much. Don't force fluids down if you don’t feel you want them
- It's likely you'll finish your race dehydrated to some extent. Sip a 500ml bottle of PH 1500 if you feel particularly fatigued or if you’re suffering with cramp
- Research shows that drinks containing sodium enable better rehydration as it allows the body to hold onto more of the fluid. Asker Jeukendrup and Lindsay Baker (2014) concluded that if you want to rehydrate quickly, then you need to drink ~1.5x more fluid than you’ve lost - and you need to make sure there’s plenty of sodium either in or with the fluid to account for your salt losses too
