This past year, we introduced a new workout every Wednesday, adding 48 new sessions to the Stryd Workout Library.

From wave tempos to long runs to hill repeats and more, each workout was created to support your running whether you were preparing for a 5k, 10k, half marathon, marathon, or simply building momentum. For December, we selected 10 standout workouts from the year and featured them in the Workout of the Week collection so you can revisit the sessions that defined 2025.

Let’s dive into the top workouts from this past year.

A Year in Review: Check Out the Most Iconic Workouts

From sharpening speed for the 5K to building endurance for the marathon, 2025 delivered a lineup of standout workouts that helped runners of all levels push their limits. In this year-end roundup, we are highlighting the most impactful and popular sessions that defined the year to make you faster, stronger, and race ready. 

New Heights

New Heights is a 5k focused session that blends short hill intervals with a steady tempo run to build strength and endurance. You will begin with six sets of thirty seconds uphill at your 5k power with easy downhill recovery jogs, shift into a smooth ten minute tempo at your marathon power on flat terrain, then finish with another six sets of thirty seconds uphill at your 5k power with relaxed downhill recoveries. Incorporate this workout early in your training block or during your base phase to lay a strong foundation for faster 5k racing.

Full Send

Full Send is a speed session designed for 5k runners to elevate top end speed and improve fatigue resistance. It begins with four sets of twenty second strides with sixty second recovery jogs, then moves into four sets of seventy five seconds at your 5k power, forty five seconds at your 3k power, and thirty seconds at your 3k to mile power to close each set. These progressive intervals sharpen your ability to handle shifting intensities, maintain speed, and finish strong. Add this workout in place of a similar speed workout or tailor it in the workout builder by adjusting the number of sets to fit your training needs.

Zoom Down & Back Up

Zoom Down & Back Up is a 10k focused session that takes you through a full range of intensities to build speed and endurance. You will run 1600 meters at your 10k power, shift to 600 meters at your 5k power, accelerate into 300 meters at your mile power, then work your way back up the ladder to finish with another 1600 meters at your 10k power. This structure challenges your ability to change gears smoothly and stay strong through rising and falling intensities. Add this workout to your training plan for a balanced session that sharpens fitness and moves you closer to peak performance.

Treadmill Lock In + Push

Treadmill Lock In + Push is a 10k focused workout designed to challenge your strength and endurance across shifting intensities. You will run four sets of three minutes at your half marathon power on a two percent incline, one minute at your 5k power on a three percent incline, and ninety seconds of easy running at zero percent. This structured blend of sustained effort and short surges strengthens your ability to hold power, respond to changes, and stay efficient when the intensity rises. Add this workout to your training plan when you need a demanding session that builds fitness.

Threshold Builder

Threshold Builder is a half marathon focused session that strengthens your threshold power and helps you run stronger for longer. You will complete four to five sets of five minutes at your half marathon power with ninety seconds of easy running between each, giving you the chance to settle into a steady rhythm and practice quick recovery while holding a sustained effort. This workout fits naturally into any phase of training, with four sets ideal for early or late cycle rhythm work and all five sets offering a mid cycle challenge that maximizes your fitness gains.

Power Shift

Power Shift is a half marathon focused session designed to build endurance, sharpen pacing, and elevate your aerobic strength. You will complete three sets of eight minute efforts with a short recovery jog between each, running the first half of every set at marathon effort before shifting smoothly into half marathon effort for the second half. The goal is to make the gear change feel controlled and efficient while maintaining steady form as the intensity rises. Add this workout to your schedule when you want an aerobic session that sharpens fitness and strengthens your ability to handle half marathon pace.

Tempo Booster

Tempo Booster is a marathon focused workout designed to ease you into steady tempo training while building strong aerobic fitness. You will complete four sets of three minutes at your marathon power followed by three minutes at an uptempo power, a structure that helps you lock into a controlled effort before easing slightly while still maintaining a high overall output. Add this workout to your schedule during your base phase or anytime you want a reliable tempo session that supports marathon training.

Equal Intensity

Equal Intensity is a marathon oriented progression session built to strengthen your aerobic base and improve your ability to hold steady effort over long durations. It features forty two minutes of progressive running, increasing intensity every fourteen minutes as you move from the lower to the higher end of Zone Two. This steady buildup helps develop fitness, deepen endurance, and reinforce efficient pacing. Add this workout to your calendar during your base phase or race specific phase whenever you want a controlled progression run that boosts marathon readiness.

Rapid Repeats

Rapid Repeats is a speed workout built to sharpen fitness and strengthen your ability to sustain hard efforts with limited recovery. You will run twelve 400 meter repeats at your 5k power with a short forty five second recovery between each, keeping your body working near threshold so you improve lactate clearance, running economy, and fatigue resistance. Add this workout to your calendar when you want a sharp, high quality session that also trains you to handle surges.

Firecracker Fitness

Firecracker Fitness is a speed workout that will have you spinning the legs for some fast repeats. You will run five sets of one minute at your 5k power, then three sets of two minutes at your 10k power, and finish with five sets of thirty seconds at your 5k power. Add this workout to your calendar to give your legs the spark they need to head into the new year ready to tackle training.
