In this training, we introduce a mental run form checklist designed to help you fight fatigue. Use these tips to avoid ‘The Marathon Shuffle’— Low swinging, scuffing heels, and heel strikes that happen when a runner succumbs to this death march of sorts. Keep your eye on the prize and run down your checklist. First, focus on keeping your shin vertical and landing with a midfoot strike. Second, continue driving forward (not up) with your knees. It’s so easy to slack on these two simple principles and start grabbing at the ground. Your mental checklist will not only keep you running faster, but it will also help you avoid that awkward ‘am I walking’ race photo.
