Why Generic Training Plans Don’t Work

Fitscore will automatically update paces to match exactly where you're at.

Most apps hand you the same plan regardless of your fitness. A 45-minute 10K runner and a 55-minute 10K runner shouldn’t train at the same pace - but they do.

RunFitCoach is different. Every pace zone is calculated from your FIT Score — a real measure of your fitness that updates as you improve. Your plan adapts when life gets in the way. And your strength work actually matches how your legs feel today.

Your FIT Score Drives Everything

Enter a recent race result. RunFitCoach calculates your FIT Score and sets five personalized pace zones: easy, tempo, interval, marathon, half marathon. Race again and the whole plan recalibrates.

Strength That Adapts to Your Day

Dead legs from yesterday’s long run? No barbell? Knee acting up? Your strength workout rebuilds itself around what’s real for you right now - fatigue, equipment, injuries, and training phase.

Plans That Bend, Not Break

Got sick? Traveling? Raced unexpectedly? Adjust any week with a simple prompt. Full plan history with undo means nothing is ever lost. Your training adapts to your life.

Real Runners. Real Results.

Built by a coach who’s been there.

Johnny Crain has run a 2:12 marathon, qualified for the Olympic Trials four times, and coached thousands of runners from their first 5K to Boston qualifiers. RunFitCoach puts that experience into an AI engine that coaches you the way Johnny would - personally, adaptively, and with decades of real knowledge behind every recommendation.
