Have you ever jumped Tryfan's Adam and Eve? If so, do you remember your first time?
If you've never attempted it, this is about as close as you can get to the real thing without risking you neck, which, incidentally, is a very real danger when you're actually up there.
Until this moment, Trail magazine's Dan Aspel had never jumped them either. It's fair to say he was nervous.
In this short video, filmed in conjunction with the British Mountaineering Council (www.thebmc.co.uk), join Dan as he musters the nerve to make the jump, and share his before and after thoughts on this most famous of mountain challenges.
Oh, and be sure to stick around 'til the end to see just how nervous he actually was...
