Our friend ironman619 is about as hard charging as they come. It seems like the guy does some sort of gnarly obstacle course race every other day, so we’re glad he found time to kick back and relax on Catalina Island recently. Just kidding, he went and did a 50k. Keep being you, Marc! Congrats on being this week’s Knock Fan Friday! For your chance to win a free pair of shades, tag us in an awesome photo of you rockin’ your Knocks and use the hashtag #knockfan.
