Last night I did my first 10-miler and felt great afterwards! I was so pumped up I felt like I could have drop-kicked a hippo and sent his girlfriend flowers. So, tonight I figured I'd easily beat that distance and then some (maybe bike to Mexico and back, no big deal), and set off only to discover that after a mile or so I was one crabby dude. Even now, although I did go 11 miles, got to blast down a couple big hills and climb another, I'm still just kind of ticked off and I don't know why.
I ate plenty today, made sure and hydrated well and took water with me, so what gives? Only thing I can figure is my body's telling me I need to take a day off, maybe? I've been riding every night since Thursday. I've never found a form of exercise I like enough to do more than a couple days in a row, so this is all pretty new to me.
