Andreas Almgren has established himself as one of Europe’s most formidable long-distance runners. With multiple national and European records and global championship medals, he continues to redefine what’s possible on the track and road.

Behind every record and fast finish is Andreas's data-driven approach to his training. Everything is built on carefully controlled threshold training and a deep understanding of numbers behind each workout.

Dive into Andreas Almgren’s training and discover how structure and consistency help him prepare to race at the very highest level.

The Structure Behind Andreas Almgren’s Training

Andreas follows a structured principle of periodization, putting together a consistent block of training ahead of a key race to test his fitness. Rather than relying on constant high-intensity sessions, Andreas builds his fitness through consistent weeks of quality work.

"I’ll keep a set structure for maybe six weeks, and adjust if needed. For example, I restarted full training in mid-November after Valencia Half Marathon with six good weeks of training, then two weeks of race prep.

I don’t think training should be too static. But once you decide on a period, you should be quite consistent within that period"

The consistency and repetition of workouts week-over-week allows him to maximize his adaptations. This also keeps a similar weekly training load throughout the block, allowing him to stay healthy.

Threshold Training

Andreas Almgren monitors his lactate and heart rate during a session.

Threshold training is the backbone of Andreas Almgren’s training. The key focus is holding the effort exactly where it needs to be. Heart rate plays an instrumental role in managing a precise effort.

"I usually check four things: speed, lactate, heart rate, and overall feeling. I get a baseline for how I want workouts to feel. It’s not just “go out and run threshold and you’re going to run fast”, there’s a lot more to it than that."

In his threshold sessions, Andreas aims for a heart rate around 167-178bpm, where he can hit paces as high as 2:40/km.

"I’ve been doing threshold training for a while, so I know how I want each workout to feel and what lactate values work for me long-term. That’s why heart-rate data from COROS is a very important part of the overall picture."

With a detailed log of heart rate and speed data for all of his sessions, Andreas uses COROS to compare his data across weeks and training blocks.

Inside Andreas Almgren's Key Sessions

3 x 3km Sharpening Workout

After building a strong foundation, Andreas ensures he is race ready through a series of key workout sessions. Ahead of Valencia 10KM, Andreas ran two key workouts to sharpen his fitness and build confidence heading into the race. At the end of a 170km week, Andreas had a hard 3 x 3km with three minutes recovery, completing his reps in 8:00, 7:52 and 7:43, this was a sign for Andreas that his fitness was in the right place.

10 x 1km Pre-Race Workout

As one of the final checks before racing, this workout, with short recoveries, shows whether Andreas can hold race pace under fatigue. If the numbers line up and effort feels controlled, it’s a clear sign he’s ready to race.

• Workout Type: Race-Pace Intervals
• Structure: 10 x 1km off 1 minute recovery
• Average Pace: 2:34 per km
• Average Heart Rate: 155bpm

Building Toward the Valencia 10K

Andreas has had a lot of success in Valencia, setting the European record in the 10KM last January and more recently the Half Marathon in November 2025. This year he heads to the south coast hoping to build on these performances.

"This year, I’ve made a few changes compared to last year. To race well in Valencia, it would put me in a very good position for the summer."

Just like any runner, Andreas hopes to improve race after race. With a bachelor’s degree in Industrial Engineering and Management, relying on high quality data is essential for him to monitor his progress.

"I want to be one of the main contenders, someone the others are chasing. I have every workout I’ve done since 2018 saved so I can compare every version of that workout I’ve ever done. I started doing this more systematically this year, and now I have every type of interval workout saved."

Many of the best athletes in the world are at the top because they remain students of the sport. They study their training, learn from their data, and constantly make the necessary adjustments. Like Andreas, you can use your COROS data to train smarter and make real progress toward your goals.
