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.

  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.

  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…
