RunLight5K

Go from zero to running 5K in 9 weeks.

No account. No ads. No subscriptions. Just open the app, pick your day, and start running.

RunLight is a 27-workout program that gradually builds you up from short run/walk intervals to running 30 minutes straight. The screen turns a different color for each phase — green for warmup, red for run, yellow for walk, blue for cooldown — so you always know what's happening with a quick glance at your phone, even in an armband. Like red light, green light, but for running.

How it works:

Each workout starts with a 5-minute warmup walk, moves through timed run/walk intervals, and ends with a 5-minute cooldown. You'll hear audio cues and feel a vibration whenever it's time to switch — even with your phone locked in your pocket or armband.

Week 1 starts easy: 60 seconds of running, 90 seconds of walking, repeat. By Week 9, you're running for 30 minutes without stopping.
