35 miles on the Landon Trail

I got the itch, so I went as far as I could go on the Landon trail (35  miles.)  I drank (sweated) 48 ounces of water plus 2 liters of water I bought at the Kwick shop. I barely made it home, and I got a head ache about 10 miles from home.  I bought some Excedrin and that fixed me up.
I drank a lot of water on this ride.
