Had to take a look Lit and like the Warning: looking directly at the Duds may result in dizziness, nausea & hypnotism. Physical effects aside, these optically-thrilling shorts will mesmerise your fellow runners and make your nether-region the talk of the running track.
I wear the mens version and they are the best shorts ever for a long run and because the pockets and elasticated gel thingys on the back are spread across the whole of the back and slightly on your side you don't notice any real weight. Having two ordinary side pockets gives you somewhere to stuff gloves on a cold morning rather than down your pants.
Seren they have a drawstring so that plus the even spread of weight doesn't give a feel they are about to come down.
What a mix of things people eat on runs. I don't think I could eat some of the high fibre things suggested without stopping for a download. What you do need though is stuff that is high on the GI list so the sugars get into your blood as quick as possible and the gels are formulated to do that. I believe even those take about 30 minutes to start to have an effect.
