Our weather for the last week has been 100+ each day. Unfortunately I live out in one of the hottest spots so I haven't done any riding around here for a few days. I can take the bike down to the coast and ride, but that would make for a 50 mile round trip in the car and with the cost of gas, I don't want to do it to often. Tomorrow they said it is suppose to cool down to about 85 in my area, that I could probably tolerate. I'm thinking of taking my camelbak with ice and water in it. I will also probably take an empty water bottle that I can fill along the way so I can pour the water on my head if I need to. I have a buff I will take that I could soak in water and put around my neck and hopefully all these things will make the ride a little more pleasant. I plan on doing my usual hilly 40 mile ride, any other suggestions for staying cool.
