He is a trail runner and a bigger guy. He’s been pushing into the longer distances; marathon and ultramarathons. He found water boy and hasn’t looked and anything else since. The workout one is a god send he took them during the last two races he ran/rucked. One being a 25mile ruck with 35lbs on his back and the other a 50k all in the hill country of Texas. Neither time did he cramp up or have any major muscle dehydration issues. That’s all thanks to water boy! He’s been using over the past year and won’t turn back, please don’t change the formula you’ve hit the nail on the head with this one!
