Yes and no. A standard headlamp is not enough, although carrying one for a backup would be a smart idea. We would recommend a light with no less than 500 lumens. The nicer the light, the brighter it will be, longer burn time, and faster charging. Backup light is a must, as it’s expected to be a “new moon” which translates to NO Moon that weekend, so if your light dies on course, it’s gonna be dark.
You will also be required to have a red flashing light on your backside, either body or bike.
