Stop Racing Your Long Runs

Learn why your half marathon long runs shouldn’t become weekly races. Coach Ray explains how controlled, conversational long runs build endurance, why pushing too hard can compromise your training, and when faster running does belong in a long run. Train with purpose, recover well, and save your racing for race day.

Your long run is one of the most important sessions in your half marathon training—but it isn't a weekly race.

It's easy to head out feeling good, notice you're running faster than planned and gradually turn a controlled endurance session into an unofficial time trial.

That might feel satisfying when you finish, but it isn't necessarily helping your half marathon training.

What Is Your Long Run Actually For?

For most runners, the primary purpose of the long run is to develop the endurance needed to run strongly for 21.1km.

That means spending an extended period running at a controlled, conversational effort, allowing the duration of the session to provide much of the training stimulus.

You don't need to finish exhausted.

In fact, I generally want you finishing a standard long run feeling as though you could have kept going if you needed to.

Don't Try to Prove Your Fitness Every Weekend

As your target race approaches, it can be tempting to use your long run as a test.

You might think that if you can run 16km or 18km close to your target half marathon pace, you've proved you're ready.

But training isn't about proving your fitness.

It's about building it.

Push unnecessarily hard during your long run and you may create extra fatigue that affects the quality of your training over the following days.

Your fitness comes from the combined effect of weeks and months of consistent training—not one impressive Sunday run.

Can You Run Faster During a Long Run?

Absolutely—but there should be a reason.

Some long runs might deliberately include sections at half marathon race pace, tempo running or a progression towards a stronger finish.

That's very different from simply speeding up because you're feeling good.

If your programme says to run faster, execute the workout.

If the session is supposed to be controlled, have the discipline to keep it controlled.

Stop Chasing the Average Pace

Instead of finishing your long run and immediately checking whether your average pace was faster than last week, ask better questions.

Did I run at the intended intensity?

Did I maintain good technique?

Did I practise my fuelling?

Did I complete the planned duration?

Can I recover properly before my next important session?

Those answers tell you far more about the quality of your training than an impressive average pace.

Save Your Racing for Race Day

You don't need to win your long run.

You need to use it to develop endurance, recover from it and continue building fitness through the rest of your programme.

Run with purpose rather than ego.

Build endurance in training. Save your best running for when there's a finish line. 🏁
