Official Sports Nutrition Partner

HIGH5 is excited to be the sport nutrition supplier for the Threshold Trail Series. Whether you are a seasoned pro or this is your first ultra, HIGH5 can provide you with that extra boost you need for those tougher miles and the hills you may come across along the route.

HIGH5 are providing participants with energy gels, energy source sachets, zero tabs and protein recovery (for those staying overnight). They will also be helping to prepare you for the Threshold Trail Series by sharing their bespoke sports nutrition guide that will help you get the most out of their products. On top of this you will get a bespoke discount exclusively for our participants to take advantage of – keep an eye out on the Participant Information Platform.

HIGH5 take great pride in the fact that for almost 20 years they have produced some of the very best sports nutrition available and are looking forward to helping our runners and walkers get to the finish line.
