We are pleased to announce our new top to bottom run competition in partnership with iON Cameras, inviting you to submit your own Top To Bottom runs this winter to win a new iON camera and a heap of Onboard stash.

Following on from the success of our Top To Bottom series launched last season, we're proud to announce that we've partnered up with iON Cameras to open the series up to you guys - the Onboard readers.

All you need to do is grab a camera, grab a buddy, and film one continuous top to bottom run at the location of your choice. Whether it be park, powder, pipe, or streets, we want to see how you guys get creative with the terrain in front of you. It doesn't have to be about stomping the hardest set of tricks, and we're equally excited to see creativity and fun coming through in your submissions.

Once you've filmed your dream run, simply head here for full instructions on how to edit and submit it.

Every month, we will pick and present the top 5 of your runs, and open it up to a public vote, with the winner being decided by a combination of the public vote result and judges decision. The winner will receive a brand new iON Air Pro™ 3 Wi-Fi Camera and a whole load of Onboard swag, including t-shirt, beanie, mittens and more (exact prizes subject to availability).
