Most runners train their fitness but never train their form. Running drills fix that — they rewire the movement patterns that determine how efficiently you run at any pace. This app puts 30+ drills in your pocket, each coached by Kathy Butler, a two-time Olympian who has spent 20+ years coaching runners from beginners to elite competitors. Warm-up drills are always free.

All current warm-up drills are always free. Activity tracking and streak celebrations are free to download, no account required. Coach sharing tools are available with a Run Foundations Annual subscription ($9.99/yr).
Strength and cool-down drills come with a built-in timer. Set the work interval, rest, repeat — the app tracks it so you can focus on form.


Coaches pick drills and share a file with one tap. Athletes import it to see a "From Coach" section at the top of their library. When they're done, they share their full activity report right back — effort ratings, session notes, 28-day trends.
Coach sharing requires a Run Foundations Annual subscription — $9.99/yr, cancel anytime.
Every time you complete a drill, it's logged. Your activity calendar shows which days you trained and how long your current streak is — the simplest motivation to keep going.


Tap Mark Complete and the app celebrates with you — confetti, a "Well done!" moment to log how you felt, and streak milestone toasts when you hit 7, 14, 30 days and beyond.

Two to three times per week is the right starting point for most runners. Kathy prescribes dynamic warm-up drills before every quality session — track workouts, tempo runs, or intervals. Foot and ankle exercises can be done daily at 10–15 minutes, since they're low-impact and build cumulative strength over time.
Always before quality sessions — after a brief easy warm-up jog, not instead of one. Dynamic drills prime the neuromuscular system for fast running. Doing them after a hard workout, when muscles are fatigued, removes their training benefit and raises injury risk.
Yes — and the evidence is consistent. Drills improve running economy by reinforcing efficient mechanics: better hip extension, higher cadence, and reduced ground contact time. Kathy has prescribed these sequences to athletes at every level, from first-time marathon runners to Olympic Trials qualifiers, with the same results across the board.
Absolutely. These videos are designed for all levels — Kathy deliberately teaches the same drill sequences to beginner runners as to her elite athletes. Start at reduced intensity and focus on form over speed. Within a few weeks the movements become second nature.
These drills are just a taste of what Kathy incorporates into her coaching. Get a fully customized plan built around your goals.
