Half distance, double delay I signed up for the Hastings Half Marathon in March 2019 and finally got to run it in March 2022 after two years of pandemic-related cancellations. I managed a time of 1:44:151 in terrific conditions and raised money for Sands, the stillbirth and neonatal death charity (at time of writing you can still donate). https://www.rostrum.blog/2021/12/30/gpx3d/ Thu, 30 Dec 2021 00:00:00 +0000 https://www.rostrum.blog/2021/12/30/gpx3d/ tl;dr You can use R to extract coordinate and elevation data from a GPX file and then plot it as an interactive 3D object. I put some functions in the tiny R package {gpx3d} to help do this.
