Race saver

I was doing a 135km closed road event and at the 40km mark I felt my right quad tightening up pre-cramp. Had one of your gels and boom - avoided cramp the rest of the event. Major shout out.

Hackney Half PB

I was handed one of these during the Hackney Half when I was really struggling. It completely turned my race around and I got an 8 min PB!

Match day essential

It's probably not going to get me goal of the season but I don't cramp if I have one of these. Way easier than prepping traditional electrolytes too.

Genuine game changer

I'm not worried about cramp anymore. I used them for my second 70.3 as I cramped so badly on my first and my race was seamless. I have my first full Ironman this year and I will be taking a few of these.

Feet cramp solved

I swim everyday and I get cramp in my feet. For years I have tried to fix it as it ruins my sessions. Now I have one of these half way through my swim and I don't cramp.

Perfect for intense training/races

I always have one before a big session and take one to two during. Plus the sunburst orange is so refreshing.

I usually start to cramp at 50km+

As soon as I start to feel my quads tighten, one of these give me a fresh set of legs instantly. So so good.

Way easier to drink than other gels

These aren't thick like other gels. They taste natural and are the perfect mix of salty and sweet. Perfect for me as I always used to cramp after 10km.

Elite gel

Court-side contingency plan for me. Use it most matches. Definitely reduced my fatigue on court.
