Sir Chris Hoy and Helen Jenkins Partner with SiS

We're delighted to welcome on board two of our latest SiS Brand Ambassadors, Olympic hero Sir Chris Hoy and triathlon world champion Helen Jenkins.

The pair, both at the top of their game in their respective sports, join the growing list of top athletes and teams that use Science in Sport products.

Sir Chris Hoy is one of the most famous names in Olympic sport. The popular multiple World and Olympic champion is Britain's most successful ever Olympian, as well as a BBC Sports Personality of the Year winner. Helen Jenkins, Great Britain's leading female triathlete, won the ITU World Championship in 2011 and 2008 and finished 5th for Team GB in last summer's London 2012 Olympics.

Sir Chris Hoy will work closely with Science in Sport and our team of experts in hydration and nutrition to help him perform to his maximum both in training and competition. Hoy will continue to use one of his all-time favourite products, SiS REGO Rapid Recovery; he'll also use the full range of energy, hydration and recovery products available from SiS.

"Nutrition plays a huge part in how well I do on the track, in the gym and out training on the roads so to be the best I can be," said Hoy. "I need to use the best nutrition possible. I have used SiS products for many years and I'm looking forward to working with them to further develop this area of my preparation and recovery."

Helen Jenkins will also work with the Science in Sport team of experts and will use a range of the brand's leading energy, recovery and hydration products.

"Having the support of SiS throughout my training and competition schedule will help to fuel my performance, and I'm really excited to be a part of the SiS team," said Jenkins. "I have my sights set on the Commonwealth Games in two years time and then Rio in 2016, and I am very excited about SiS being a part of this journey with me."
