A runner on my team took a nasty spill this weekend on a running path. (26)She was running along, lost her footing, and was suddenly sprawled out, with a bloody knee and hands. Although running isn’t a contact sport, lots of runners fall and get pretty banged up. Often someone or something else such as a cyclist, another runner, or bad conditions is to blame for a wipe-out, but sometimes it’s just our own clumsiness. Follow these tips to help prevent falls during your runs: First, pay attention. (27)Keep your head up and look ahead about 10 to 20 feet in front of you. Try not to look down at your feet, so you can see what’s coming. Not only is this important for your safety, it’s also proper running form. This is especially important when running on trails or roads with lots of holes and stones. We have a lot of these on our running routes these days. Then make sure your shoes are tied. This may seem common sense, but I’m surprised at how many runners I see with dangling shoelaces. Most shoelaces on running shoes are extra long, so be safe and double-knot them. Moreover, you should watch out for cyclists and other runners. (28)Avoid collisions with other runners or cyclists by always being aware of your surroundings and practicing good communication. If you’re approaching another runner or cyclist and need to pass them, let them know on which side you’re trying to pass. Before you stop or turn around, look back and make sure your path is clear.
