Context hikr.org is a platform where users can post reports about their ski tours or hikes. Some of these posts also contain the original GPX file as it was recorded during the activity. Content This dataset consists of a sample of approx 12000 such GPX files which were scraped from their website in Spring 2018. The GPX tracks were simplified with gpxpy to reduce the size of the dataset, additional features such as max_elevation etc. were also calculated with gpxpy. The difficulty rating of the hikes is based on the SAC Hiking Scale and has been set by the users who did the hike. Acknowledgements Thanks a lot to hikr.org and their users for providing these information publicly. Inspiration How long do you think that hike will take?
