Im away to spain for 16 days holiday and im going to be taking my bike along to keep my training going along and was looking for some tips etc regarding warm weather training.

As coming from country(uk) when it becomes 23C sees people running to the parks to sunbathe, im not used to training in hot climates.Ive got some hilly races when i get back home which i hope to try and get some training in the hills on holiday and get in some general high end training which I am doing back home.Im just want to be cautious so that I dont get dehydrated and get the most from the 2 weeks or so I am there.

plenty of isotonic drinks?out early or late in the day? any tips would be great cheers
