Been out running for an hour or so... ouch. Went to Sonning, which is quite pretty; I've actually cycled this route before. Perhaps I ought to try and dig out how long it took that time and compare. Hm.

Actually, I just measured that on map24, and it works out to about 10Km. So that's actually a pretty good time, considering how long I've (not) been running, and the condition I'm in.
