I've used and still use the following for running, which includes anything from a quick hour around the local woods on the fire roads to all night ultras in the Lakes, Peaks and Alps coving technical ground, with fast descents.
Petzl Myo XP - Good light throw, boost mode for navigating/picking out features, careful management, one set of batteries will last a night. Good build quality, light weight and well balanced on the head.
Alp-Kit Gamma - Cheap, but seems to last. Decent run time. Rear red LED so really handy if running on the road or in a group. Good as a spare/shorter/less tech runs.
LED Lenser SEO5 - Very light & compact, bright, good run time, comfy, better build quality than the H7, lasts all night, but when it runs out of battery there is minimal warning (It does flash, but then goes, no taper in light). My current light of choice for most ultras and tech running.
Glow-Worm X2 - Slightly heavy, external battery pack which is rechargeable, good run time, but heavy battery... but these are mega bright being MTB lights, which convert to a head lamp. Over kill for running, unless well you can... I rarely take these out, but sometimes its fun to light the world up. But only used on shorter 4-5 hour runs. The X1 would be a better option, which I'm planning on getting this winter, again mostly for the bike, but also some harder runs.
