RunPact

What it does

Most training apps were built for road runners and stop at the marathon. Ultrarunners stitch together PDFs, spreadsheets, and a GPX viewer that has no idea what 9,000ft of climb does to your pace. RunPact is built ultra-first: 3D flythrough of any GPX, terrain-adjusted pacing, and ML predictions trained on real ultras, adaptive plans you can fork, customize, and share — no $300/mo coach required, Strava + Intervals.icu sync, more on the way. €3/mo. 14-day trial, no card.

Ultramarathon training plans built from race-specific templates, plus GPX course analysis, 3D race flyovers, and ML-powered finish-time predictions.

Know your finish time, and exactly how to train for your race. Terrain-aware predictions and adaptive plans for ultrarunners — with a 3D course flythrough so nothing surprises you on race day. Start from a RunPact template, pick a community one, or build your own — set every phase, session type, intensity, and volume target. The engine generates your weekly schedule and adapts as you train. Upload any GPX file to explore your course in 3D, analyze difficulty, and get segment-by-segment pacing strategies. Our race models are trained on iconic courses around the world — then applied to whatever GPX you bring. Less than a pair of trail shoes, for the whole year.

  3D Terrain simulation for hiking, skiing etc.2025 · github.com · ▲150

  I'm working on a GPS track visualizer for quite some time. It shines in hilly and mountaineous terrain (where a 3D view makes more sense), but it also offers quite a lot of Strava-like features (statistics etc.). You can upload your GPX and FIT files manually, or sync directly with Garmin, Coros and Polar. See https://cubetrek.com for the live app and check out some examples there. It's free and opens source. Also, anyone who likes to work with 3D visualizations (especially Babylon.js), let me know if you like to help polish this thing further.

  Runo 2.0Jan 2026 · runoapp.com · ▲132

  I built Runo after years of inconsistent marathon training. GPS watches tell you your pace AFTER it's too late. So I made a simple metronome that plays a beat at your target cadence (steps per minute). New in 2.0: Apple Watch haptics (run to the beat without headphones), Strava sync, and social features. 4.7 on App Store, 10k+ runners. Would love feedback from the HN community.

  I made a running app that turns your runs to a virtual garden2025 · runandgrow.com · ▲36

  I started running 5 years ago and it completely changed me. Recently, I decided to train for my first marathon and needed something more than just tracking my runs to motivate me. I noticed all the apps currently available are just trackers and route finders, but nothing has solved the problem of consistency. So I thought of combining the basic idea of the Forest app with running and created a small app for myself which would reward me with plants and trees for my runs. I am not a mobile developer but then i came across Capacitor. Since I knew Next.js and have been working with it for the…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
