There's something special about preparing for your first marathon. The excitement. The anticipation. The sense that you're about to do something you've never done before. But there's usually a fair bit of uncertainty too! And from speaking to hundreds of runners over the years, I've noticed that people tend to worry about different things. For some, it's whether they'll be able to cover the distance. For others, it's pacing. Some worry about hitting the wall. Others are concerned about nutrition, cramping, or simply how they'll feel in those final few miles. And here's something worth remembering. You don't have to eliminate every worry before you run your first marathon. But you can prepare for many of the things you're worried about. You can practise your fuelling. You can develop a sensible pacing strategy. You can build your endurance progressively. And you can learn how to manage the inevitable challenges that come with running 26.2 miles. So here's today's question: If you're preparing for your first marathon, what's the ONE thing you're most concerned about? 1. Completing the distance. 2. Getting my pacing right. 3. Fuelling and avoiding the wall. 4. Injury, recovery or something going wrong. 5. Something else entirely. And if you've already completed a marathon, I'd love you to join in too. What was your biggest worry before your first marathon, and did it turn out to be justified? Share your experiences below. Your answer might help somebody who's preparing for theirs. John
