How can everyone be so fast?

I know speed is relative and that this sub has slower runners. But I feel like in real life I have yet to find somebody who consistently runs and is slower than me.

I’ve been running for nine months now after a 6 year break and I run 3 times a week: one speed session, one easy run and one long run where I mix easy and tempo paces. I also strength train once a week. I’ve ran two half marathons in the past 9 months. Even with all this training my half marathon time was still 2h20min.

I’m not that new to running. I’ve ran on and off my whole life. Meanwhile there’s so many people I know who haven’t ran before and sign up for a half marathon with the goal just to finish..and they end up with a sub-2h half.

Even at my fittest in my twenties my fastest half was still 2h3min. Am I just destined to be a slow runner forever or what am I doing wrong?
