The best water bottles to keep you hydrated during running

Posted by for Strength

We’ve found lightweight, packable and easy to hold bottles to keep you hydrated during your summer runs.

Heading out for a jog in bright sunshine sounds like a dream. Until you realise that with running in temperatures in the high 20s comes a lot of sweat, heavy breathing and a very dry mouth.

Unfortunately, keeping hydrated while you’re out means carrying a bottle, and a standard one just won’t do. Taking your usual metal chiller on your run can feel as though you’re lugging a 10kg dumbbell with you, which won’t help you nail that sub-30 minute 5k.

There’s an alternative, of course. You can purchase super lightweight, easy to hold bottles for no more than a few pounds. Be prepared for your warm weather runs to change for the better.
