Have you ever bitten off more than you can chew but knew there was no going back? If you are a runner then you may be more than familiar with this feeling of dread mixed with inevitability that can hit you even when you are doing something you actually enjoy. You might feel this way when a little bad weather is dialled up to biblical while you are still mid-run. Or maybe you face this whenever you step up to a new starting line for the first time. Even runners who appear fearless will experience this same feeling when they attempt to do something that is just a little outside their comfort zone. Fortunately, one of the universal truths of running also happens to be the well-known saying, that ‘what doesn’t kill you makes you stronger’. In other words, having the resilience to overcome whatever challenge is in front of you can be immensely rewarding.
