Should You Warm Up for Running?

Your trainers are laced up, running vest secure, Strava set. You’re ready to get out on your next training run. Time is tight. Can you skip your warmup and have more time on the pavements? Or is skipping your warm-up a recipe for an injury?

As both a physio and a performance-driven runner, I always try to fit in a solid warm-up before a run. Beyond the physiological benefits, it really helps me get into the right headspace to push my body. However, it may not be essential for everyone. The answer to “should I warm up before running” lies in your goals, pace, and physiology.

Why people warm up

A good warm-up helps your body ease into movement, particularly if you’ve just got up for an early run or have been sitting at a desk working. As you start to stretch, move dynamically or jog, your heart rate will increase. This will boost blood flow, deliver more oxygen to your muscles and make you feel warmer. At the same time, your joints loosen, and your muscles become more flexible and ready for the demands of running.

A good warm-up is particularly important if you want to run faster, as it reduces the sudden stress placed on your body. Without this preparation, areas like the knees can take on more strain if the surrounding muscles are not ready to support them. Warming up reduces the risk of injury by gradually preparing your tissues for running.

Personally, the few times I have skipped the warm-up, my body feels shocked and uncomfortable, and it struggles to hit pace early.

I find there is a mental benefit to warming up, too, especially on race day. While I love the buzz and excitement at the start of the race, I find that a warm-up away from the crowd gives me time to gather my thoughts and prepare for the upcoming physical and mental challenge.

Why some runners avoid a warm-up

Not all runners need the same preparation. If you’re conservatively pacing yourself or running at a leisurely pace, the risk of injury is lower. In these cases, a warm-up could still help with joint mobility and mental readiness, but it’s less essential.

There’s also the consideration that if a runner is about to run a distance that is long for them, whether it is a 5k, 10k or ultra, an extra warm-up might deplete much-needed energy stores. In these cases, dynamic stretches and gentle walking may be enough.

Is a warm-up right for you?

For competitive runners and those seeking performance times, the answer is a strong yes, you should warm up before running. The physiological and psychological benefits are too valuable to skip. But, for more recreational runners, a full warm-up might not be necessary.

If you’re trying to decide whether to warm up before running, ask yourself a few questions.

1. Am I running very fast today?
2. Am I going for a PB?
3. Am I trying to hit a fast pace early in the run?
4. Do I need some alone time before my race?

If the answer is yes, you should warm up before your run to perform better and reduce your risk of injury.

If you’re running slowly or have a gradual lead-up to a pace planned, the first ten minutes of the run might be enough to get your muscles and joints ready for the demands of your movement.

Your warm-up might include dynamic drills, strides, a jog, some stretches, or just walking to the start line. Tailoring your approach to your goals and needs is what truly makes a warm-up “worth it”.
