Fartlek Runs: The Unstructured Speed Workout Taking the Running World by Storm

Fartlek runs are having a moment in the running community. But what exactly are they, and why are they suddenly everywhere? Let’s dive into this trending workout that’s got runners buzzing.

What’s the Deal with Fartleks?

“Fartlek” might sound like a made-up word, but it’s actually Swedish for “speed play.” It’s a type of running workout that’s all about mixing things up – alternating between fast and slow segments. But here’s where it gets interesting: there’s no strict structure. You’re not timing yourself or hitting specific paces. It’s all about feeling the run.

But wait, there’s a twist. Some runners are pushing back on this definition. Is it still a fartlek if you’re using time-based intervals? What if you know exactly how long each segment will be? The debate is heating up in running forums and subreddits.

The Great Fartlek Debate

Let’s break down what most runners and coaches agree on:

• It’s a mix of fast and slow running
• The slow parts are still running, not walking
• No need for precise paces or times
• Fast segments are short, slow segments are longer
• You decide when to speed up or slow down
• It should feel harder than an easy run

But here’s where it gets controversial. Some argue that true fartleks need to be completely random, with a coach blowing a whistle to signal pace changes. Others say as long as you’re varying your speed, it counts.

Why Fartleks Are Blowing Up

Fartleks are gaining traction for several reasons:

1. Mental Break: No strict pacing means less pressure
2. Gateway Workout: Great for transitioning from easy runs to structured speedwork
3. Less Boring: The variety keeps things interesting
4. No Comparison: Every fartlek is different, so no pressure to “beat” previous times

But here’s the real kicker: fartleks are perfect for our current “always on” culture. They’re flexible, adaptable, and let you tune in to your body’s needs. It’s like the athleisure of running workouts – casual but effective.

How to Fartlek Like a Pro

Ready to jump on the fartlek bandwagon? Here are some trending ways to do it:

The Playlist Fartlek

Sync your run to your music. When the beat drops, you drop into a faster pace. It’s like creating your own running soundtrack.

The Hill Fartlek

Use your environment. Hit the hills hard, then recover on the flats. It’s nature’s interval workout.

The Light Pole Fartlek

Popular in urban areas, this involves sprinting between light poles or other landmarks. It’s like a real-life video game.

The “Haul Ass” Fartlek

This one’s going viral on Reddit. Pick certain spots on your route as “haul ass” segments. Or, if a specific song comes on shuffle, it’s sprint time.

The Partner Fartlek

Take turns setting the pace with a running buddy. It’s competitive, social, and a great way to push each other.

The Treadmill Fartlek

Perfect for gym rats. Change something every quarter-mile – speed, incline, or just how hard you’re pushing.

The Bottom Line

Fartleks are more than just a workout – they’re a philosophy. In a world of structured training plans and data-driven workouts, fartleks offer a refreshing alternative. They’re about listening to your body, having fun, and maybe even rediscovering the joy of running.

So, are you ready to join the fartlek revolution? Lace up, head out, and let the speed play begin!
