OpenAir Tools is a free collection of outdoor planning, performance and tracking tools for hikers, runners and adventurers. Built by the team behind Big Trail Adventures, the brand combines specialist outdoor knowledge and proprietary spatial datasets with AI to create practical, intuitive tools for real-world trail and running needs.

For planning, users can explore UK running routes with Skamper, build detailed hiking and trail-running itineraries, identify the best season for a trail, and estimate route times using distance, elevation, terrain and pace. Other tools help hikers create personalised kit lists and track progress towards summiting the 214 Lake District fells, with maps and achievement cards.

For performance analysis, OpenAir offers Terrain-Adjusted Grade calculators for parkrun courses in the UK, Ireland, Australia and New Zealand, as well as a predictor for comparing race times across distances and terrain. Veteran fell runners can also use a handicap calculator based on SLMM standards.
