The Rurilab Blog

Notes on data-driven running: how Rurilab turns your real training data into an adaptive plan, who it's built for, and the science underneath it.

Ultra & trail

Training for a mountain ultra: vertical gain, time on feet and pacing

Why vertical gain and time on feet matter more than mileage, how to pace by effort, and how terrain specificity protects your race.

Product

How Rurilab works: a training plan engineered from your real data

From your completed workouts to a daily verdict — how the app reads your data, estimates your fitness, and adapts your plan week to week.

Who it's for

Who Rurilab is for (and who it isn't)

Built for endurance — half and full marathon, ultras and mountain/trail — where a science-based, adaptive plan helps most, and where it doesn't.

Data

Keep your running data without a Strava subscription

Strava changed API access for free accounts. Here's how to keep analysing your training — via Health Connect, Apple Health and file import.

Science
