5 HIIT Running Workouts to Help You Run Faster
With the 2026 Little Rock Marathon behind us, a lot of runners in Little Rock, Arkansas are already logging miles and hoping their pace improves before next year’s race.
But here’s the truth:
If you only run long and slow, you’ll get good at running long and slow. If you want to get faster, you need to train faster. That’s where HIIT training comes in.
At our gym in the Riverdale district of Little Rock, we use High-Intensity Interval Training (HIIT) in both our personal training programs and HIIT bootcamp classes to build speed, power, and endurance — whether someone is training for a marathon or just trying to feel stronger.
Here are five HIIT running workouts that can help you improve your speed safely and efficiently.
1. Sprint Intervals (Speed Builder)
Best for: Improving raw speed and finishing strong in races.
How to do it:
Warm up with a 5–10 minute easy jog
Sprint hard for 30 seconds (90–100% effort)
Walk or lightly jog for 60 seconds
Repeat 6–8 rounds
Short bursts of max effort train your fast-twitch muscle fibers and improve your ability to accelerate. These are especially helpful for runners trying to shave minutes off their 5K or half marathon times. Try doing these on a track, flat road, or treadmill to control pace.
2. Hill Sprints (Strength + Power)
Best for: Building leg strength and running efficiency.
Find a moderate hill (we have plenty around Little Rock).
Sprint uphill for 15–20 seconds
Walk back down for recovery
Repeat 6–10 times
Hill work strengthens your glutes, hamstrings, and calves while improving stride power. Many of our personal training clients use hill intervals to prevent plateauing during marathon prep.
3. Fartlek Training (Controlled Chaos)
“Fartlek” means speed play — and it’s great for breaking up boring runs.
During a 20–30 minute run:
Pick landmarks (mailboxes, street signs, trees)
Run hard to one
Recover to the next
Repeat throughout the run
This improves pacing awareness and mental toughness — both critical during longer races like the Little Rock Marathon.
4. Tempo + Speed Finish
Best for: Improving endurance and your ability to push when tired.
10-minute easy warm-up
15 minutes at a “comfortably hard” pace
4 x 30-second sprints with 30 seconds rest
5-minute cool down
This trains your body to handle speed after fatigue sets in — exactly what happens in the last miles of a race.
5. HIIT Treadmill Pyramid
Perfect for unpredictable Arkansas weather.
30 seconds fast / 30 seconds easy
60 seconds fast / 60 seconds easy
90 seconds fast / 90 seconds easy
60 seconds fast / 60 seconds easy
30 seconds fast / 30 seconds easy
Repeat 1–2 times. Pyramid intervals challenge multiple energy systems and keep your workouts efficient — ideal if you’re balancing training with work and family.
Why HIIT Makes You a Faster Runner
Adding HIIT workouts 1–2 times per week can:
Improve running speed
Increase cardiovascular capacity
Strengthen key muscle groups
Boost calorie burn
Reduce overall training time
Most runners overemphasize mileage and underemphasize strength and power. That’s why we combine strength training and HIIT conditioning inside our gym.
Speed isn’t just about lungs — it’s about muscle strength and efficiency.
