The New Running Routine: Miles Plus Muscle
Strength training for runners is the growing practice of combining traditional run workouts with structured resistance sessions to improve durability, performance, and long‑term fitness while reducing the likelihood of overuse injuries. Garmin’s latest user data shows how quickly this model is spreading. Pulling from its watch ecosystem, the company reports that runners recorded nearly 13% more indoor and 3% more outdoor running activities in 2025 compared with 2024, and logged 23% more weeks that included both a run and a strength session. That pattern lines up with the boom in weightlifting and hybrid events such as Hyrox, as well as runner‑focused strength classes emerging in boutique studios. Instead of seeing cross‑training running workouts as optional extras, more athletes are building them into weekly plans, looking for smarter ways to balance volume and strength without slipping into burnout.
Why Cross-Training Running Sessions Cut Injuries and Boost Speed
The shift toward cross-training running programs is driven by performance and injury data more than trends. Runners who add strength work develop better joint stability, stronger connective tissue, and improved posture under fatigue, all of which help protect against common overuse problems. Strategic lifting also increases force production and running economy, helping athletes hold pace with less effort. Garmin’s figures show that running is now a mainstay habit rather than a seasonal phase, with average distances around 4.8 miles per run and many users logging 6–20 miles per week. As consistency rises, the need for supportive strength training grows too. Sessions focused on compound lifts, single‑leg stability, and trunk strength give the body a buffer against higher mileage. Instead of adding endless easy miles, runners are using strength sessions to sharpen performance while keeping weekly stress at manageable levels.
How GPS Watches Are Catching Up to the Way Runners Train
As training becomes more varied, GPS watch strength tracking has evolved from a basic add‑on to a central feature. Traditional running watches were built to track pace, distance, and splits outdoors, with quick one‑button starts and options for intervals or treadmill sessions. Now, many devices include dedicated profiles for strength training, indoor workouts, and even hybrid races, so runners can log lifting alongside long runs in the same system. Fitness‑oriented watches often go further, adding lifestyle metrics such as sleep and recovery, which help athletes understand how strength days affect their readiness for key workouts. According to Women’s Running’s watch guide, most devices offer GPS as standard plus optical heart‑rate tracking, with some models supporting chest straps for more precise zone work during intervals. The result is a more complete picture of runner fitness data instead of a narrow view of cardio alone.
Using Runner Fitness Data to Balance Strength and Mileage
The real payoff from better strength tracking comes when runners use data to fine‑tune their weekly mix. With every run and lift logged, it becomes easier to see how changes in volume or exercise selection impact pace, heart rate, and perceived effort. Garmin notes that nearly 40% of its runners average 6–10 miles per week, with another 28% between 11–20 miles, suggesting plenty of room to adjust mileage relative to strength work. Athletes can monitor patterns such as rising resting heart rate or poorer sleep after heavy lifting days, using that feedback to schedule easier runs or extra recovery. Over time, GPS watch strength tracking paired with run metrics helps runners answer key questions: how many lower‑body sessions can they handle, when to taper strength before races, and how to keep progressing without tipping into fatigue.
