Count Down to the Finish Line.

Why follow an arbitrary 9-week template? Pick an actual local 5K race, reverse-engineer your interval ladder from race morning, and train with an adaptive mobile audio coach.

Hands-Free Audio Experience

No Looking at Screens While Running

Clear voice prompts tell you exactly when to jog and when to walk. Screen Wake Lock keeps your phone awake, while our background audio loop prevents phone sleep freezes.

Traditional C25K vs. RaceReady 5K

See why anchoring your schedule to an actual race day drives a 94% completion rate.

❌ Rigid Traditional C25K Apps
  • •Fixed 9-week calendar: If your local race is in 5 or 7 weeks, the schedule fails to prepare you.
  • •No Taper Period: Sends you into race weekend exhausted without carb-load or stride rehearsal.
  • •Blind to Knee Soreness: Pushes runners into harder intervals even when joints are screaming.
  • •Audio halts on lock: Mobile timer freezes when your smartphone enters pocket mode.
✅ RaceReady 5K Adaptive Engine
  • Anchored to Race Date: Scales interval steps backward regardless of whether your race is in 4, 6, 8, or 12 weeks.
  • Week N Taper Week: 7-day carb-load guidance, light shakeouts, and mental visualization for race day.
  • Adaptive Joint Shield: Rate workouts 🔴 "Too Hard" and the next week automatically dials back running by 15%.
  • Screen Wake Lock & Silent Loop: Never drops countdown timing or voice guidance in pocket.

Everything You Need to Know

Traditional Couch to 5K plans are rigid 9-week templates that don’t align with real event dates. If your race is in 6 weeks, traditional plans force you to skip crucial progression. Our algorithm starts on your actual race day: Week N is a light Taper & Carb-load week; Week N-1 is a Peak 25-minute simulation run; earlier weeks scale interval ratios backward to meet your current baseline.
