Matsmum, many of us triathletes empty gel packets into our water bottles for the bike and run segments of a triathlon, makes nutrition really easy although I usually supplement with ginger cake, mmmmm, and ginger is anti-emetic as well, good if you tend to suffer nausea when your system is getting tired. Plus I find I do need some solid food too. The triathlete's secret weapon is gummy bears or jelly beans, don't know anyone who doesn't have some of them tucked into their food box on the bike along with salted nuts and/or pretzels! Actually I'm lucky, I haven't had a problem taking gels anyway. I prefer a brand called "Hammer", they are a bit more runny, not quite so viscous as other brands. Honey Stingers are good too.
Very sensible Matsmum, stay safe please. Northern Germany has taken a battering too, so far here in the south we've escaped lightly, although the forecast hail and snow did show up this morning as I was driving to work. All gone now though and the sun is shining. Pretty windy outside still.
