If it lasts, though, I'd see a doc for a check up. You never know. Maybe your thyroid is working overtime?

Thanks - I'm pretty sure it's the increased riding. I seem to have gone to the "next level" recently. 3 personal bests in the last ten days - a flat ride, a MB ride and a climbing ride I do regularly. All of them huge increases, or decreases if they're time based.
