Description

Hydration is one of those things that sounds simple, but during longer training it can become the thing that quietly unravels a good session.

If you’ve ever finished a long run or ride with salt marks on your kit, felt heavy legs earlier than expected, or struggled to drink enough water when it’s hot, there’s a good chance electrolytes are part of the answer.

Styrkr SLT+ is built for those situations.

It delivers a high dose of sodium alongside potassium, magnesium and calcium — the key electrolytes lost through sweat during endurance exercise.

What we like about it is the simplicity.

It’s not trying to be a fuel drink.
It’s not trying to be everything at once.

It’s a strong, clean electrolyte solution that lets you manage hydration separately from energy intake. That means you can combine it with gels, chews or drink mixes depending on the session.

For runners, cyclists and triathletes training in warmer weather, on longer rides, or simply sweating a lot, that flexibility can make a real difference.

Sometimes it’s not about adding more carbs.
It’s just about replacing what you’re losing.

Typical Use Cases

SLT+ works particularly well for:

• Marathon and ultra running
• Long cycling rides
• Triathlon training
• Hot weather training blocks
• Heavy sweaters needing more sodium

When to Use Electrolytes Like SLT+

Electrolytes become increasingly important when:

• Exercise lasts longer than 90 minutes
• Training takes place in warm conditions
• Sweat rate is high
• Salt marks appear on clothing or skin after sessions

Replacing electrolytes helps support hydration, muscle function and overall endurance performance.

Why Ready Sweat Go loves Styrkr SLT+

Electrolytes can be one of the most overlooked parts of performance endurance.

Many athletes focus on carbs, but during longer events sodium loss through sweat can become the limiting factor.

We like SLT+ because it keeps hydration simple and flexible.

It delivers a strong electrolyte dose without adding carbohydrates, which means you can adjust hydration separately from fuelling depending on conditions, intensity or personal preference.

In practice that means:

• Add electrolytes to plain water

• Combine with gels or drink mixes

• Increase intake on hotter days or longer efforts

It’s a straightforward, no-nonsense solution that fits easily into most endurance nutrition strategies.

And unlike traditional electrolyte tabs, these handy little packs are extremely portable, great for taking with you on events or longer training sessions.

FAQs

What makes SLT+ different from regular electrolyte drinks?

SLT+ is designed specifically for endurance sport and contains one of the highest sodium doses in its category.

This makes it particularly useful for long sessions, hot weather or athletes who lose large amounts of salt in sweat.

If you cramp regularly during your longer efforts, this could be the electrolyte your looking for.
Does SLT+ contain carbohydrates?

No. SLT+ contains electrolytes only.

This allows athletes to manage hydration and fuelling separately, combining it with gels, chews or drink mixes depending on their needs.
Who should use high-strength electrolytes?

High-strength electrolytes are particularly useful for:

• endurance athletes

• heavy sweaters

• hot race conditions

• long training sessions

If you notice salt marks on clothing after exercise or experience cramping in longer events, additional sodium may be helpful.
Is SLT+ vegan and allergen friendly?

Yes. The product is vegan, gluten-free and dairy-free, with a short ingredient list focused on the key electrolytes required for hydration.
Can I combine SLT+ with energy gels or drink mixes?

Yes. In fact this is often the best approach.

Many endurance athletes use electrolytes for hydration and carbohydrates for fuel, adjusting each depending on the conditions and intensity of the session.
