Victor Ducray is a full-stack developer and ultra-trail runner who combines his two passions by building digital tools for people who run long-distance trail races. His personal brand brings together running, software development, race experiences, and a candid perspective on the challenges of the sport. He shares race reports, professional insights, and reflections on training, equipment, and life on the trails through his blog and online channels.

Victor’s running tools help athletes plan, understand, and explore their races. RunCut creates a pacing plan from a GPX file, including goals, aid stations, and kilometer-by-kilometer splits. MyFinishTime predicts finishing times for more than 200 UTMB races using 124,000 real results, while Vas-tu DNF? estimates a runner’s likelihood of withdrawing. Ultra Destin is an interactive game about shaping a trail-running career, and TrailReview helps runners discover smaller trail races.

The site also presents Victor’s race history, upcoming goals, professional background, and gallery. Across both his products and personal projects, he connects practical technology with the realities of ultra-running.
