I cycle to uni and find that when I get there I often feel very sleepy during lectures - I know this is a common side effect of lectures but I am more tired than I was before I cycled in. I have cycled for around 8 months now and it is only 6 miles to uni (takes around 26-30mins average speed 12-13mph).
I tried drinking lucozade once when I got to uni and I felt much more awake, however I don't like the sugar content! Would something like electrolyte replacement drinks help? I read that you only need them after exercising for at least an hour or more. Or are there other options, i.e. perhaps a banana?
Not adrenaline. It's low blood sugar. If you don't want sweet, sure, banana is good. You probably burn 300-400 cal. riding in, so you want less than that. Fig Newtons are good, 'cause you can eat a couple right away, then maybe another later. Piece of bread and cheese, good too, to keep going until lunch. Electrolytes won't help at all.
