Im pretty sure SIS are the nutritionists from Sport England. If im right, theres definitelly some cutting edge stuff there, a collegue of mine used to work for Sport england and some of the experiments they undertake are pretty extreme.

The gels they do for marathons are the best going, you dont need to take water with them.

If you go on the Rugby bit (About us /Energy Systems) and you can see what they suggest for rugby league

not surprising really given how hard league players have to work in their sport than players in the other rugby code, many of whom are overweight and unfit.

perhaps youd see an add for union players in a donught or pizza shop

will take a look at them if I can ship them for my long distance kayaking event in August.

yeah start at the water in perth and head west. dont turn back.

gel based stuff is just sugar carbs

try superpump 250 by gaspari for energy, nitric oxide based

or poison by ALRI fat blaster / energy
