A ride around Howth with MAD (Mountainbiking Association of Dublin). Ross McClure is first down the scree slope, followed by Noel Carr. Mick McCutcheon speeds down the hill and nearly flies into oblivion. Saved from death by Noel Carr. Gregor descends on his fully rigid Rockhopper. The rest of MAD do the walk of shame down the scree.
