About
myWindsock is a cycling-focused weather intelligence tool that goes far beyond generic forecasts. Riders can upload GPX, TCX, or FIT files to instantly visualize headwinds and tailwinds along their planned route, allowing smarter pre-ride decisions. The platform integrates directly with Strava, Garmin, and Wahoo, enabling automated post-activity weather reports added directly to Strava descriptions and email summaries after every ride. The AI Athlete feature analyzes your past activities to learn your performance profile, then applies that knowledge to predict wattage requirements and estimated times under current or forecast conditions — both on the road and on a turbo trainer via Feels Like Elevation™ simulation. Competitive cyclists can dig into segment-level weather data, filtering for tailwind opportunities or reviewing leaderboard conditions to contextualize their personal bests. For event-specific preparation, myWindsock supports UK time trial events and weekly Parkruns with purpose-built forecast tools. The Planner lets users schedule future rides and monitor forecast windows for optimal conditions. Premium subscribers unlock the Spatial 3 weather engine, which resolves weather by elevation, distance, and time for ultra-high-definition data, as well as advanced pacing experiments, interval tools, and full Strava leaderboard weather history. A free tier is available with core route and weather features, making it accessible for casual and competitive cyclists alike.
Key Features

- AI Athlete Performance Prediction: Learns from your past activities to predict wattage requirements and finish times under real or forecast weather conditions, on the road or turbo trainer.
- Segment & Leaderboard Weather Analysis: Filter segments by wind direction to find tailwind opportunities, and review the exact weather conditions behind any Strava leaderboard effort.
- Spatial 3 Premium Weather Engine: High-definition weather resolution that accounts for elevation, distance, and time to deliver the most accurate micro-forecast available along your route.
Use Cases
- Planning a sportive or gran fondo route by identifying sections with significant headwinds to pace appropriately and conserve energy.
- Preparing for a UK time trial event by analyzing forecast conditions on the course and adjusting target power or gear selection accordingly.
- Reviewing Strava leaderboard times to understand which top efforts were set in favorable tailwind conditions versus true benchmark performances.
- Checking Saturday morning weather for a local Parkrun to decide on clothing layers and realistic finish time expectations.
- Using the AI Athlete tool to predict finishing time on a new route based on personal fitness data and the upcoming wind forecast.
