Training science, technical deep-dives, and the messy details of building a tool for ultra runners.
Two runners. Same distance. Same goal time. Wildly different races. If your training doesn't account for the terrain you're actually running on, you're preparing for the wrong event.
Read field noteNot every ultra is the same race, and not every plan should be the same plan. RunPact now ships with six purpose-built training templates — each one a different blueprint for a different kind of ultra.
A massive amount of work has gone into RunPact since January. Here's what shipped, where we stand, and why we're confident a soft launch is coming very soon.
There's no TrainerRoad for ultrarunners. Most plan generators assume flat roads and marathon distances. We built something different — and it's just getting started.
A quick recap of what’s shipped since November and what we’re finishing next. Soft launch target: April 1, 2026.
We've been busy making RunPact better. New button design throughout, intelligent pace predictions for hilly runs, easier workout logging, and tons of fixes based on your feedback.
In an era where AI has become a buzzword, we want to be transparent about what actually powers RunPact's race time predictions. Spoiler: it's not a large language model, and it doesn't use any trendy AI techniques you're probably thinking of.
Since mid-August, we've been busy polishing existing features and adding new capabilities. Here's what's new in RunPact: enhanced training plan creation, improved 3D visualization, and a complete Stripe integration for subscriptions.
A look into the technology that powers our platform, our new 3D course visualization, and what's on the roadmap for ultra runners.
