Were you riding on a rougher road than normal? Maybe tense about the route? I have had that when doing a very hilly (and thus lots of downhills and braking) ride. I also have had it when I have done longer rides and rode on extended amounts of rough pavement. Sometimes my hands are sore after mountain biking where I am braking a lot. I am not sure if any of those apply to you?
