For Runners
Structured running plans with Karvonen HR zone caps, session types, and a weekly structure built around your goals. Every morning, your coach checks your HRV, sleep, and resting heart rate. When your body says pull back, your coach is already ready with options.
Melde detects cardiac drift by comparing your heart rate in the first and second half of the run at the same effort. A drift above 5% signals cardiovascular fatigue your legs haven’t felt yet.
When your cadence coefficient of variation crosses 15%, it signals technique breakdown under fatigue. That's an early warning your legs are sending before pace ever drops.
How much slower was your last quarter compared to your first? Pace fade reveals whether you went out too hard, hit a fueling wall, or simply ran out of aerobic capacity. Melde computes it automatically and surfaces the fade in your coaching context, so your next readiness assessment accounts for it.
Melde tracks your elevation gain and vertical ascent rate, giving your coach the context to interpret a hilly effort differently than a flat one. A 10K with 200m of climbing tells a different story than a flat 10K at the same pace, and your coaching reflects that.
Melde calculates your personal HR zone boundaries using the Karvonen formula, which factors in both your resting heart rate and max heart rate for individualized zone precision. Your Zone 2 cap isn’t a generic percentage. It’s computed from your actual physiology, and it updates as your fitness changes.
Every morning, your signal shapes your coaching options. HRV dropped and sleep under six hours? Melde presents options: hold the planned threshold run, shift to Zone 2, or take a recovery day. You decide. After the run, the debrief analyzes what happened. By evening, tomorrow’s coaching already reflects today’s data. Your weekly template stays consistent. Your daily coaching adapts to how your body is actually responding.
Run Monday, ride Tuesday, swim Wednesday. Melde computes training impulse (TRIMP) for every session using gender-specific constants, so your weekly load accounts for everything, not just your runs.
For runners who want structured plans, science-backed recovery signals, and coaching that adapts to your body. Not the other way around.
