Perfect for trail running. Which is why I bought this lamp based on another user's review. It's pretty light and super bright. I originally tried the Vectra IQ, but that was way too heavy for running. Plus it ran off of 4 AA batteries and the Zenix only uses 2. I love the fact that the Zenix puts out a white beam as opposed to a yellow one too.
