Trail running hydration belt (option to add a water bottle and available in multiple colours)
When I got back into trail running my wife bought me an older version of this belt. This belt must have been run for 100s of miles as my wife uses it now and she used it for her couch to 5k and continues to take it out with her on her runs. I've used this to train and run a half marathon in.
It houses storage for a water bottle and has enough room to store keys, money and phone will be hard pushed to fit your wallet in there. However, you can fit a few gels and an energy bar or 2 in there to fuel up if you need those extra carbs to give you a boost.
If you want a 600ml water bottle included in your purchase make sure you select the option which states that a water bottle is included.
