Major new features, significant improvements — and sometimes, the idea comes straight from the field.
Access your personal space to manage your profile, view your saved analyses and update your preferences. A centralised hub for all your Segly race plans, reachable in one click from anywhere on the site.
A visual timeline dynamically shows the time distribution across your segments. At a glance, see where the effort concentrates, how the sections balance out and which segment will weigh most on your race.
Choose your preferred unit format — distance in km or miles, speed in min/km or km/h — and Segly remembers it. Your preferences are saved and applied automatically to all your future sessions.
Move the boundary between two segments precisely using a new dedicated modal. A surgical tool for refining your splits to the metre, directly on the map — without having to recreate your segments from scratch.
💡 Idea by Julien
The fatigue factor now adapts to the length of your race: short trail (≤6h), mid trail (6–20h) or long ultra (>20h) — with default values and labels calibrated for each format. The simulation range extends up to ±70% for unlocked accounts.
The Road Book tab now shows an optimistic (−10%) and cautious (+10%) passage range for each segment, alongside the estimated time. This range is also included in the condensed PDF export — giving you a complete race plan with all three scenarios in a single document.
💡 Idea by Julien, Terrain Advisor
Analyse a training run and get 4 realistic race time estimates — slower than your training pace by progressive factors. Perfect for anticipating your competitive performance on the same track.
💡 Idea by Mathias
A library of major races already segmented by the Segly team: UTMB, Templiers, SaintéLyon, Grand Raid, GRF… Import the track directly and find the official segments, key passage points and field data — no setup needed.
Complete overhaul of the manual segment editor. Split, merge, rename and reorder your segments directly on the map with metre-level precision. The most comprehensive segmentation interface available.
Choose how Segly displays your speeds: min/km, km/h or corrected climb pace. The format applies across the whole interface — tables, charts, sharing — to match exactly how you think about racing.
Segly calculates your carbohydrate, sodium and hydration needs segment by segment — accounting for elevation, forecast weather and estimated duration. A nutrition plan built directly into your race plan, ready to share with your support crew.
Access weather forecasts at every point of your route — temperature, wind, precipitation — up to 10 days before the start. No more surprises at altitude at 3am.
Split each segment into sub-segments to refine your plan around an aid station, a technical passage or a key col. The granularity that demanding runners were waiting for, without losing the big-picture readability of the race.
Generate a sharing link to send to your team. They see your segments, estimated passage times, notes and the weather at every point — without needing to create an account.
Enter your ITRA score, UTMB Index, Be Trail level or VMA — Segly calibrates the time estimate to your real profile, factoring in elevation gain, terrain technicality and forecast weather. No more randomly chosen goals.
Each segment displays its real slope profile — with detection of walls over 20%, deceptive false flats and technical descents. A visual read that replaces averages that say nothing about the real terrain.
First public release of Segly. GPX analysis, automatic segmentation, time estimation and elevation visualisation: the foundations of the tool that would become ultra-trail runners' favourite race assistant.
