How to Calculate Your Split Times on a Trail Run with Segly

On a trail run, knowing what time you’ll reach a specific aid station or the top of a climb is crucial for managing your race and reassuring your loved ones. Here’s how to use Segly to estimate your split times.

Why estimate your split times?

The Naismith Method

The classic formula for hiking allows for 1 hour per 5 km on flat terrain, plus an additional hour for every 600 m of elevation gain. For trail running, you can adjust this based on your fitness level and the technical difficulty of the terrain.

Segly makes this calculation easy

By segmenting your GPX track by key points or distance, Segly provides the following for each segment: distance, elevation gain, average gradient, and duration. Simply apply your personal coefficient to get a reliable estimate of your estimated time.

Export to take the data with you
