Science in Sport backs a number of elite endurance events and the JCP Swansea Half Marathon, which takes place on June 26, now forms part of its exclusive sponsorship portfolio.
Runners will be fuelled with SiS GO Isotonic Energy Gels at mile six and nine and SiS REGO Rapid Recovery sachets will be in the goody bags at the finish.
Ashley Read, marketing director for SiS, says: “Cementing our position as the brand for runners is a key part of our strategy in 2016, both in the UK and internationally.
“The JCP Swansea Half Marathon has been growing participation each year and we’re looking forward to adding value to the runners’ preparation and race day experience.”
