So I've been planning my tour for a while now and at this point I've bought all the supplies, booked flights and all that jazz. In short, I don't think cancelling it is an option. The thing is, I foolishly didn't predict that hot weather might be a problem and now I learn that South of Europe Experiences a heatwave with temperatures in Spain (where I'm headed) reaching 40C (that's ~105F). This is slightly... no, rather very concerning.
Does anyone have experience touring in such extreme temperatures? Would I be fine with a lot of water, salts and cycling only in early mornings and late evenings?
