One number that tells you if you're ready to race. The HARDN Score combines seven weighted factors — fitness, training completion, vert progression, freshness, taper status, consistency, and mental readiness — into a single score from 0 to 100.
Every ultra runner obsesses over mileage. But being ready for race day is about more than volume. The HARDN Score tracks what actually predicts whether you'll finish strong or blow up at mile 60.
Your chronic training load — the aerobic engine you've built over weeks and months. Higher CTL means your body can sustain more effort on race day.
How many of your planned sessions you've actually completed. A perfect training plan means nothing if you only did half of it.
Are you hitting your elevation targets? For mountain ultras, vert readiness is just as important as mileage.
Training Stress Balance — the gap between fitness and fatigue. As you taper, this rises, telling you your body is recovering.
How close you are to race day and whether your training load reflects an appropriate taper.
Your training streak — consecutive weeks you've maintained your plan without major gaps.
Tracks mood, energy, motivation, confidence, stress, sleep quality, and sleep hours through daily check-ins.
HARDN Score = Fitness × 0.25 + Training × 0.20 + Vert × 0.15 + Freshness × 0.10 + Taper × 0.10 + Consistency × 0.10 + Mental × 0.10
CTL and TSB are useful numbers — but they only tell part of the story. No other platform combines physical metrics with training adherence, elevation specificity, and mental state into a single actionable score.
A composite readiness metric from 0 to 100 combining seven weighted factors into a single number reflecting race day preparedness.
Above 75 means well-prepared. 50-75 means on track with gaps. Below 50 means behind schedule.
Chronic Training Load — accumulated fitness over roughly 6 weeks reflecting training stress absorbed.
Training Stress Balance. TSB = CTL - ATL. Negative means carrying fatigue; rises during taper.
