Runcon Reads the Race Before You Run It
A French-language route-analysis tool that turns GPX files into effort-colored profiles, difficult sections, estimated race times, and pre-race briefings.
Field notes
Runcon takes a GPX route as its starting point and breaks it into effort-relevant sections rather than presenting elevation as a single undifferentiated curve. The homepage’s example uses a 42.2 km marathon with 348 m of ascent, 45.1 km of equivalent flat distance, and a hardest segment at km 8–9.5. It also describes separate road and trail thresholds, runner-specific pacing derived from previous races, and post-race comparison intended to refine later estimates.
