I run at 7min miles along the Thames out in bucks with mine without any problem (it is a petzl tikka xp2) although I think the Cree one that ewanmac has recommended is both cheaper and brighter..
Or you could go to battersea park and use their track I believe quite a few clubs train there on a Tuesday - cycle there as a warm up and cycle home instead of a cool down...?
Or buy a head torch?
