NRTH vs PB

NRTH is adaptive training for hybrid athletes, built around a community that keeps you accountable. Your plan responds to every session you log, and the people you train with are right there to push you on. Your training lives in Blocks: Endurance, Strength, Weight Optimisation, Skill and Mobility. Choose the ones you want and NRTH builds your week around them, then adapts as you go. Lifts progress, core holds build, and your runs anchor to paces from your real race times. Whether you're laying down your first base or chasing a Hyrox podium, the plan scales to where you are and gets harder as you do. Every athlete gets a unique @handle, your identity across the app and a shareable link to your profile, with your training, challenges and milestones all in one place. The supporter feed brings your people's training together too: their workouts, milestones and 15-second challenge clips, all in NRTH's card style. Respect and comment on what they do, get a notification when someone supports you back, and keep each other going. You stay in control of what you share. Weight and life-context are private by default, and everything else is your call, kept to yourself or shown off to the NRTH community. Start training for free, and with NRTH Pro when you want more.

PB-Runner is a running app that records your runs with the full depth your watch/phone can capture - pace, distance, splits, heart rate, and running-form metrics like power, ground contact time, vertical oscillation, stride length and cadence - and shows them in detail with route maps. - Record runs on Apple Watch (standalone, phone left at home) or on iPhone. - Garmin Support with PB-Runner ConnectIQ app - Detailed run breakdowns, route maps, and splits. - Create custom training schedules with AI you can follow on your wrist/phone with audio and haptic cues. - Recovery context from Apple Health (resting heart rate, sleep, HRV, VO2max). - An analytics dashboard on the web at pb-runner.com. - Share your run with a built-in editor for sharing your runs — stats over the map or your photo, dragged into place and styled to match. Bring your own AI (optional): connect an AI you already use - Claude, ChatGPT, Gemini or another - to your own training data and build your Athletes Profile so it can analyse your runs and help plan your sessions based on the athlete you are, not a generic runner in an age group . PB-Runner is the connector; the AI is your own separate subscription, and the app works fully without it. PB-Runner is free while we launch - record runs, sync across your devices, and see your stats. Connecting your own AI is included free for now but will become a paid option later; your recording and history stay free. Privacy: your health and location data is used only to run the features you use, never for advertising, and never sold. It is only shared with an AI when you explicitly choose to connect one.
