On proper topographic maps that keep working without signal. Every activity measured the way its own sport is measured, live tracking your people can actually watch, and a log worth looking back at, in 3D.
Record on the phone or bring a file from your watch. Distance, time and climbing for everything, then the numbers that belong to your sport: pace and cadence for running, power for the bike, descent and run count for a ski tour, pace per 100 m for a swim. Ascent is corrected against the terrain rather than summed from noisy GPS altitude, so the figure is one you can actually compare.
Drop the day's pictures into the log and they pin themselves along the elevation profile, at the minute and the altitude you took them.
Share a link and whoever is waiting sees you move. Three levels of check in with an acknowledgement when they read it, and it works from a satellite messenger where there is no phone signal.
Every recording plays back over the real terrain, and live tracking is 3D too: whoever is watching sees the ridge you are on, not a dot on a flat sheet.
Our own topographic maps with hillshade and 200 m contours, plus offline regions you draw yourself and carry on the phone. No dead map above the treeline.
Plan on the real trail network with the surface and the climbing shown before you go, then turn a route into a course with checkpoints and a clock.
Your section and your Tuesday night, with season leagues and timed segments per sport. Events get registration forms, QR check in at the start and published results.
A triathlon, a hike then a swim then a hike, a ski tour with the ride home. One recording, split into legs, transitions counted properly, each leg measured on its own terms.
