Power gel headache!!
Hi all, I have used powergels on 3 different occassions ie. mountain biking in wales and 2 time trials and on all 3 occassions they have given me a splitting headache, i thought at first it was due to dehydration but i am now suspecting that it is the gels? has anyone got any thoughts on this as i would really like to have this handy energy supply without the headache!
